<description><![CDATA[Sebuah jaringan dapat juga dibedakan berdasarkan metode transmisi yang digunakan dalam peoses pengir]]></description>
<content:encoded><![CDATA[<div class='snap_preview'><p>Sebuah jaringan dapat juga dibedakan berdasarkan metode transmisi yang digunakan dalam peoses pengiriman data. Secara umum metode transmisi yang sering digunakan dibagi menjadi 2 yaitu <em>Baseband </em>dan <em>Broadband.</em></p>
<p><em><!--more--></em>a. Baseband</p>
<p>Pada metode ini, dta yang berupa sinyal digital langsung dikirim melalui media transmisi satu channel seperti kabel, tanpa mengalami perubahan apapun. Dengan cara ini, maka pengiriman data tergantung pada jarak transmisi dan kualitas media yang digunakan. Pada metode ini, dibutuhkan peralatan multiplexing yang disebut time division multiplexing (TDM). Dengan menggunakan peralatan ini, maka:</p>
<ul>
<li>· Menghemat biaya penggunaan saluran komunikasi.</li>
<li>· Kapasitas saluran komunikasi dapat dimanfaatkan semaksimal mungkin.</li>
<li>· Ada kemungkinan dari beberapa terminal dilakukan transmisi data menuju satu titik yang sama.</li>
</ul>
<p>TDM ini digunakan untuk transmisi data dalam bentuk sinyal. Dengan TDM pengiriman data dilakukan dengan mengatur pengiriman data dari masing masing termidal dengan mengatur waktu. Setiap terminal diberi jatah waktu pengiriman, bila waktunya habis maka akan diberikan ke terminal berikutnya. Demikian seterusnya hingga ke terminal terakhir, lalu dikembalikan ke terminal pertama. Proses ini berlangsung cepat, sehingga seakan-akan semua terminal melakukan pengiriman data secara bersama-sama. Oleh karena itu diperlukan media transmisi yang berkualitas tinggi, dapat mengirimkan data dengan kecepatan tinggi diantara transmiter dan receiver.</p>
<p>Keuntungan dari sistem ini adalah:</p>
<ul>
<li>· Biayanya murah, karena dalam sistem ini tidak diperlukan modem.</li>
<li>· Bentuk topologinya sederhana.</li>
<li>· Mudah dalam instalasi dan <em>maintenance.</em></li>
</ul>
<p>Selain keuntungannya, sistem ini juga memiliki kekurangan antara lain:</p>
<ul>
<li>· Kapasitas pengiriman data sangat terbatas karena hanya terdapat satu lintasan data, sehingga hanya satu pasang komputer yang dapat saling bekomunikasi pada saat yang sama.</li>
<li>· Jarak pengiriman sinyal listriknya terbatas.</li>
<li>· Untuk area yang luas diperlukan biaya instalasi yang banya.</li>
</ul>
<p>b. Broadband</p>
<p>Metoda ini digunakan untuk mentransmisikan sinyak analog. Maka apabila dalam bentuk sinyal digital, dipelukanmodem untuk mengubahnya dalam bentuk sinyal analog. Media yang digunakan adalah kabel coaxial broadband yaitu dengan menggunakan media frekuensi radio atau satelit. Data dari beberapa terminal dapat menggunakan sati terminal, tetapi frekuensinya berbeda-beda, sehingga pada saat yang bersamaan dapat dikirimkan beberapa frekuensi.</p>
<p>Keuntungan dari metode ini adalah:</p>
<ul>
<li>· Kapasitas pengiriman data yang tinggi karena memiliki beberapa sinyal transmisi.</li>
<li>· Untuk sistem broadband non kabel wilayah jangkauannya akan lebih luas dan biaya yang lebih murah.</li>
</ul>
<p>Sedangkan kerugiannya adalah</p>
<ul>
<li>· Harga modem yang diperlukan mahal.</li>
<li>· Waktu tunda perjalanan sinyal dua kali lebih lama.</li>
<li>· Proses maintenance cukup sukar.</li>
<li>· Biaya frekuensi yang mahal.</li>
</ul>

<content:encoded><![CDATA[<div class='snap_preview'><p>I&#8217;ll be tearing down the basics of unlocking a baseband along with a few examples (My &#8220;examples&#8221; are iPhone related baseband hacks) I.E What&#8217;s needed and how it&#8217;s used. </p>
<p>Now first of all, this completely legal, safe, and not &#8220;wrong&#8221; in anyway, as the proof lies in the DMCA. You should read it, it&#8217;s a nice set of copyright laws..</p>
<p>This is Reverse Engineering. Anyone can learn it. C++ along with some ARM Assembly and perhaps a little cryptography (which I personally think is a pain in the butt to learn and have completely abandoned it) should get you started.</p>
<p>First things first, you need an<br />
exploitable crash. An exploit we need here is some sort of crash that leads to a buffer overflow. A buffer overflow wil allow you to execute unsigned code (basically whatever you want).The overflow is used as the injection vector since we can inject our own code into the baseband bootrom. In this case, we want a payload to be run. A payload will take advantage of the exploit and put it to good use. Write up a decent payload and perhaps a nice little GUI to go along with it, and you&#8217;ve got yourself an unlock! Yay!</p>
<p>Now let&#8217;s take a look at an example. Since the iPhone is a big part of unlocking and 3rd party applications, let&#8217;s use that. Back on the 3.0 firmware, the iPhone baseband was numbered 04.26.08. That baseband had an AT+ command that was able to fully crash the baseband. Now, you know you have a crashed baseband when you see something like this from your terminal screen:</p>
<p>AT<br />
OK<br />
AT<br />
OK<br />
AT<br />
OK<br />
AT<br />
OK</p>
<p>The command just so happened to contain a buffer overflow, so basically the crash was used as the injection vector. A payload was written (codenamed ultrasn0w by the iPhone Dev Team) and the unlock was made.</p>
<p>Now you have to be careful with an unlock. Finding a permanent one is NOT easy. You should have a timing impact to think about the better time to release it. I.E When the next software update or hardware update becomes available. </p>
<p>So there&#8217;s my example. I&#8217;ll probably do a post about executing unsigned code on the bootrom. But for now, there&#8217;s my Baseband teardown.        </p>

<content:encoded><![CDATA[<div class='snap_preview'><p>Rumors are flying&#8230; and we are trying to control the truth. But there is talk of releasing sn0wbreeze by Halloween. According to a Tweet made by iH8sn0w today 10-19-09 &#8220;iWonder if a breeze will come on Halloween! <img src='http://s.wordpress.com/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> <a rel="bookmark" href="http://twitter.com/iH8sn0w/status/5003934183">about 1 hour ago</a> from web&#8221; and here is a new <a href="http://www.youtube.com/watch?v=8Xv1v--C94w" target="_blank">teaser</a>. Waiting for this is going to be like waiting for Christmas, you know you are going to get something cool you just hope it&#8217;s not a sweater.</p>
<p>sn0wbreeze is going to be much like blackra1n but should help you preserve your baseband being that it basically a port (Winblows version) of Pwnage Tool. You should enjoy the app when it is out. Until then keep your ear to the ground and eyes on the screen!</p>

<content:encoded><![CDATA[<div class='snap_preview'><p><a href="http://www.strategyanalytics.com/default.aspx?mod=Biography&#38;a0=2220">Sravan Kundojjala</a> of the market analysis and research firm <a href="http://www.strategyanalytics.com/">StrategyAnalytics</a> has a report out today on ST-Ericsson. The report brief says</p>
<blockquote><p>ST-Ericsson has a very strong position in all the technology pieces required to compete in the cellular chip market including basebands, RF transceivers, connectivity and multimedia. The company has a strategic IP portfolio, well established customer relationships, and also spends close to 20 percent of its revenues on R&#38;D. However, ST-Ericsson has some execution challenges in the near-term to successfully integrate the assets and cultures of NXP, ST Microelectronics and EMP.</p></blockquote>
<p>As I wrote <a href="http://deviceconvergence.wordpress.com/2009/09/13/st-ericsson-strategy-and-outlook/">earlier</a>, I agree with him.</p>

<content:encoded><![CDATA[<div class='snap_preview'><p>Nachdem sich Apple mit Firmware Version 3.1 einen ganz schönen Schnitzer erlaubt hat (Akkuleistung bei mir nach Update drastisch verringert, iPhone bleibt manchmal schwarz wenn ich es versuche einzuschalten, generell iPhone Bedienung träge, Tethering nicht mehr möglich), habe ich mich entschlossen, einen Downgrade auf Version 3.0.1 durchzuführen.</p>
<p>Dazu sei erwähnt, dass ich weder einen Jailbreak noch Sim-Unlocker verwende und je verwendet habe. Ich will also als ganz normaler Benutzer wieder die alte Version aufspielen.<br />
Hier mein Erfahrungsbericht, gleich vorweg: funktioniert eigentlich ziemlich problemlos, bis auf die Wiederherstellung der alten Daten: SMS können nicht mehr wiederhergestellt werden (wohl aber aus einem bestehenden Backup exportiert &#8211; hierzu später mehr), die Fotos waren auch weg, konnte ich aber ebenfalls aus dem Backup extrahieren. Auch die Anordnung der Menüicons wurde nicht wiederhergestellt.<br />
Zeit fürs Wiederherstellen: etwa 1,5 Std.<br />
Ich verwende ein iPhone 3G, Mac OS X Snow Leopard und iTunes 9.0.1.</p>
<h2>Datensicherung</h2>
<ul>
<li>Zunächst möchte ich sicher gehen, dass alle Daten gesichert sind. iPhone anschließen, Datensicherung durchführen.</li>
<li>Anschließend im Finder ins Library Verzeichnis des Benutzer gehen (normalerweise unter /#startvolume#/Users/#benutzer#/Library/ bzw. /#startvolume#/Benutzer/#benutzername#/Library/)</li>
<li>Dort ins Unterverzeichnis &#8220;Application Support/MobileSync&#8221;</li>
<li>Hier sollte nun ein Ordner namens &#8220;Backup&#8221; sein. Dieser Ordner beinhaltet die Backups. Diesen Ordner einfach kopieren(!) und woanders hin speichern, damit sind wir auf der sicheren Seite.</li>
<li>Wer ganz sicher gehen möchte, kann auch noch die Kontakte und Kalender sichern (wieder im User Library Ordner &#8220;Application Support/AddressBook&#8221; bzw. &#8220;Calenders&#8221;)</li>
</ul>
<h2 style="font-size:1.5em;">iPhone Firmware Downgrade</h2>
<ul>
<li>Version 3.0.1 der iPhone Firmware holen (direkt von Apple):<br />
<a href="http://appldnld.apple.com.edgesuite.net/content.info.apple.com/iPhone/061-6974.20090731.Cf4Tg/iPhone1,1_3.0.1_7A400_Restore.ipsw">iPhone 3.0.1 download (<strong>iPhone1,1_3.0.1_7A400_Restore.ipsw</strong>, 229 MB)<br />
</a><a href="http://appldnld.apple.com.edgesuite.net/content.info.apple.com/iPhone/061-6972.20090731.Zx3Rr/iPhone1,2_3.0.1_7A400_Restore.ipsw">iPhone 3G 3.0.1 download (<strong>iPhone1,2_3.0.1_7A400_Restore.ipsw</strong>, 230 MB)<br />
</a><a href="http://appldnld.apple.com.edgesuite.net/content.info.apple.com/iPhone/061-6976.20090731.Vgbt5/iPhone2,1_3.0.1_7A400_Restore.ipsw">iPhone 3GS 3.0.1 download (<strong>iPhone2,1_3.0.1_7A400_Restore.ipsw</strong>, 298 MB)</a></li>
<li><a href="http://www.benm.at/?dl_id=363">iRecovery OS X</a> holen und installieren (Download bei <a href="http://www.benm.at/tutorials/howto-iphone-3g-firmware-3-1-downgrade-os-x/" target="_blank">benm.at</a>)</li>
<li><a href="http://www.benm.at/?dl_id=362">LibUSB OS X 10.6 Snow Leopard</a> holen und installieren (Versionen für andere Betriebssysteme unter <a href="http://www.benm.at/tutorials/howto-iphone-3g-firmware-3-1-downgrade-os-x/" target="_blank">benm.at</a>)</li>
<li>iPhone anschließen (sofern nicht schon geschehen)</li>
<li>Im iTunes das iPhone auswählen und auf der rechten Seite mit gedrückter Alt-Taste (Mac) bzw. gedrückter Shift-Taste (Windows) auf &#8220;Wiederherstellen&#8221; klicken.</li>
<li>Heruntergeladene Firmware auswählen</li>
<li>&#8230;warten&#8230;</li>
<li>iTunes meldet einen Fehler &#8220;1015&#8243; &#8211; das ist normal und kommt immer, wenn man eine ältere Firmware Version einspielt, im konkreten Fall hat das mit dem Baseband zu tun, das mit 3.1 upgedatet wurde</li>
<li>Wiederherstellung abgeschlossen, iPhone müsste jetzt einen USB Stecker anzeigen</li>
<li>iTunes schließen</li>
<li>Ein Terminal Fenster starten (zu finden unter /Programme/Dienstprogramme/Terminal.app)</li>
<li>Folgende Befehle nacheinander eingeben (immer warten, bis Reaktion kommt):<br />
iRecovery -s<br />
printenv<br />
setenv auto-boot true<br />
saveenv<br />
reboot</li>
<li>Das iPhone startet nun neu, sobald es sagt, es will mit iTunes verbunden werden, iTunes wieder öffnen</li>
<li>iTunes aktiviert nun das iPhone (evtl. Netzbetreibereinstellungen können aktualisiert werden)</li>
<li>Anschließend fragt iTunes, ob das iPhone als neu behandelt oder aus einem Backup wiederhergestellt werden soll. Je nach Wunsch, ich habe wiederherstellen aus dem Backup gewählt.</li>
<li>Nun läuft die Wiederherstellung bzw. Synchronisierung und das wars&#8230;.fast, denn erstens kommt es anders und zweitens als man denkt:</li>
</ul>
<h2 style="font-size:1.5em;">Probleme während des Downgrades</h2>
<p>Es traten einige Ungereimtheiten während des Downgrades auf, die sich jedoch alle mehr oder weniger aufwändig beheben ließen.</p>
<ul>
<li><strong>iPhone bootet immer wieder in Wiederherstellungsmodus</strong> &#8211; hier half über iRecovery folgende Befehle einzugeben:<br />
setenv auto-boot true<br style="border:0 initial initial;margin:0;padding:0;" />saveenv<br style="border:0 initial initial;margin:0;padding:0;" />/exit<br />
eine genaue Anleitung hierzu findet sich auch hier:<br />
<a href="http://mobilewebexperience.com/systeme/iphone/iphone-von-recovery-mode-endlosschleife-befreien-howto/" target="_blank">http://mobilewebexperience.com/systeme/iphone/iphone-von-recovery-mode-endlosschleife-befreien-howto/</a></li>
<li><strong>iPhone scheint kurz in iTunes auf, verschwindet aber gleich wieder und es steht am iPhone Bildschirm &#8220;Synchronisieren&#8221;</strong> &#8211; Neuinstallation von iTunes behob das Problem (einfach nach &#8220;itunes download&#8221; googeln)</li>
<li><strong>SMS sind verschwunden</strong> &#8211; anscheinend dürfte die 3.1 SMS Datenbank nicht mit der 3.0 SMS Datenbank abwärtskompatibel sein. Obwohl erfolgreich wiederhergestellt, sind keine SMS da. Diese lassen sich jedoch aus dem Backup als HTML, PDF oder Excel Datei wiederherstellen, nämlich bei <a href="http://www.iphone-sms.com" target="_blank">www.iphone-sms.com<br />
</a>Ich gehe davon aus, dass in zukünftigen Firmware Versionen (z.B. 3.2) theoretisch die SMS aus dem 3.1 Backup wieder eingespielt werden könnten.</li>
<li>Fotos sind verschwunden &#8211; auch die Fotos waren weg, konnten aber aus dem Backup extrahiert werden, nämlich mit dem <a href="http://supercrazyawesome.com/" target="_blank">iPhone Backup Extractor</a></li>
</ul>
<p>Ich würde nach dem ganzen Zauber das iPhone nochmals neu starten.</p>

<content:encoded><![CDATA[<div class='snap_preview'><p>Infineon is a formidable force in RF transceivers and is one of the predominant baseband suppliers. Forward Concepts <a href="http://www.fwdconcepts.com/dsp62409.htm" target="_blank">ranks</a> them #3 globally in total baseband (2G, 3G). Although Infineon’s visibility increased tremendously after design wins in the iPhone, it has been a longtime supplier of RF solutions to LG, Nokia, Samsung, and Sony-Ericsson. The company shipped its billionth RF transceiver in November 2007.</p>
<p>Infineon rightly predicted early on that handset market would polarize towards low-cost devices and high-end smart phones. Providing single-chip platforms for low cost phones is a forte of Infineon. The investments paid off. Infineon earlier this year shipped its 100 millionth single-chip solution. The technical superiority of this platform received a strong vote when Nokia chose Infineon as a baseband supplier for its EDGE platforms. Infineon competes directly with ST-Ericsson for low-cost phone designs.</p>

<p>High-end phones from Apple and RIM have been using Infineon’s 3G baseband and RF solutions. LG, already a big customer of Infineon’s single-chip phone platform for low-cost devices, announced the coming of a slew of smart phones in the next 18 months. Alongside ST-Ericsson, Infineon is likely to have scored some design wins for some of these phones.</p>
<p><strong>On the Winning Side</strong></p>
<p>The wireless semiconductor space has witnessed an abundance of activity in the past few years. On some occasions, winners were picked based on technological prowess. On others, winners were picked just by virtue of past associations. There were other times when action taken by others enriched or depleted a company’s revenue. Infineon was on the winning side, mostly.</p>
<p>– Infineon is one of the companies that stand to gain from the consolidation in baseband market. Acquiring LSI mobility gave it a strong foothold in the baseband space and some top handset makers as customers. Infineon is just one of four companies to have more than a 5% share of the baseband market. Infineon now boasts of supplier relationships with several major handset vendors.</p>
<p>– Nokia’s multi-sourcing strategy gave more power to Infineon, which is among those players poised to gain from TI’s exiting the merchant baseband business.</p>
<p>– Not long ago, Motorola held the second spot among top handset makers. Samsung then displaced Motorola. Thanks to Infineon acquiring LSI mobility, Samsung is now a major customer of Infineon’s HEDGE solution. Samsung’s market share gains will translate in part to Infineon’s gaining market share.</p>
<p>– Handset market polarization towards low-cost phones and high-end smartphones matches Infineon’s strengths well.</p>
<p>Is this a coincidence or strategic thinking on Infineon’s part? Either way, it augurs well for sustained growth of the company’s WLS division.</p>
<p><strong>Lost 3G at Nokia</strong></p>
<p>Infineon used to supply just GSM platforms to Nokia which, at the time of diversifying its sourcing vendors, extended the relationship and added Infineon as an EDGE platform supplier. Nokia is known to have thoroughly evaluated various vendors before picking suppliers for various technologies. Not wanting to repeat the mistake of putting all its eggs in TI’s basket, and with Infineon already supplying GSM and GPRS parts, Nokia chose not to source 3G parts from Infineon. Instead, Broadcom and Qualcomm were chosen to provide Nokia’s 3G baseband needs. Interestingly, Infineon licenses its 3G stack to Broadcom. This is a loss due to strategic more than technical reasons.</p>
<p><strong>Innovation</strong></p>
<p>Infineon announced improved versions of all of its single-chip solutions. These integrate baseband, power management, RF transceivers, FM radio and in some cases media players and external memory card support. Packing its renowned strengths in baseband, power management, and RF into a single solution results is an offer that is hard to resist for any cost conscious phone designer. Although most of these are meant for the GSM and EDGE markets, such tightly integrated platforms will have a good uptake in price-sensitive 3G markets that do not demand all the bells and whistles of advanced phones.</p>
<p>Infineon announced developing a Software Defined Radio platform, XMM™ SDR 200, that can support multiple standards using the same baseband part. It gained a design win for use in satellite/terrestrial hybrid phones from SkyTerra and TerreStar. While this could go the way of <a href="http://www.sramanamitra.com/2008/03/31/chips-and-infineon" target="_blank">earlier announced</a> GSM/Wi-Fi mobile platform, the SDR platform with its low power consumption might be a hint of things to come.</p>
<p>In sum, Infineon continues to be a strong player in RF transceivers, baseband, and phone-on-a chip platforms for low-cost phones. In the next post, we will continue with the portfolio analysis and concentrate on what ails Infineon’s wireless business.</p>

<content:encoded><![CDATA[<div class='snap_preview'><p>Chào các bạn!</p>
<p>Tôi là người mới sử dụng iphone, chẳng biết gì nhiều. Mới đây may được ke_da_tinh171717 giúp đỡ tận tình mới đưa được con iphone lên 1.1.4 ngon lành. Thế nhưng tôi cùng chưa hiểu hết ngọn ngành iphone ra sao . Có làm gì thì cũng chỉ có theo hướng dẫn của các bạn mà làm theo chứ không hiểu gì. Bởi vậy rất mong muốn tìm hiểu iphone từ nhưng cái căn bản nhất. Bài dưới đây là tôi lược dịch theo nguồn http://www.hackint0sh.org/forum/showthread.php?t=32703<br />
mong muốn chia sẻ với những người mới sử dụng giống như tôi kiến thức, khái niệm căn bản. Nếu có gì sai sót, các bạn vui lòng góp ý. Thanks</p>
<p><!--more--></p>
<p>KHÁI NIỆM JAILBREAK, ACTIVATION và UNLOCKING</p>
<p>JAILBREAK là gì?</p>
<p>JAIL Break là bước đầu tiên trong quá trình hacking iphone.Khi mà iphone ở trong tình trạng nguyên bản từ nhà máy ra thì các file hệ thống của nó được bảo vệ rât tốt. Để đơn giản hơn, hãy tưởng tượng iphone là một cái xe ô tô . Apple muốn bạn ngồi sau xe, và đây là nơi mà bạn thưởng thức nhạc, video, wallpaper hay là photos. Apple hài lòng khi để bạn ngồi ghế sau của xe, đưa bạn chạy lòng vòng trên con đường mang tên AT&#38;T. Nhưng bây giờ bạn muốn lái xe thì sao?<br />
Những con iphone của chúng ta được ví giống như xe thùng của cảnh sát. Ngăn cách giữa ghế sau và ghế trước là một cánh cửa thép to lớn và nặng trịch. Làm thế nào để vượt qua được cánh cửa này? Lúc này là lúc chúng ta cần đến JAILBREAK. JAILBREAK là một quá trình đưa bạn ra khỏi hàng ghế sau, lên ghế trước nơi mà bạn có thể cầm vô lăng, đạp pedal, điều khiển radio, còi xe..vv. Khi iphone đã JAILBREAK, bạn có toàn quyền điều khiển con dế của mình, bạn có thể chạy bất cứ chương trình gì trên iphone giống như bạn có toàn điều khiển chiếc xe của chính mình.</p>
<p>ACTIVATION (kích hoạt)<br />
Từ góc độ liên tưởng con IP của mình là chiếc xe thùng cảnh sát, thì activation có nghĩa là bị cầm giữ. Apple muốn bạn để cho AT&#38;T trói chặt bạn, ngồi yên vị ở hàng ghế sau. Và đương nhiên, nếu bạn là khách hàng của AT&#38;T, bạn có thể thực hiện activation mà không cần đến JAILBREAK. Còn nếu không phải là khách hàng của AT&#38;T thì sao?Đây là lúc mà bạn hiểu rõ hơn JAILBREAK có ý nghĩa thế nào. Một khi IP đã JAILBREAK, bạn có thể tiếp cận với các file hệ thống của IP, do đó việc giả mạo một activation trở nên khá đơn giản. Khi dịch đến đây, tôi nhớ lại trước kia khi mua mới một simcard của Vina, mobifone ..sau khi lắp vào máy thì cần phải chờ một khoảng thời gian để sim được kích hoạt và khi đó thì bạn mới có thể nhắn tin, thực hiện cuộc gọi thoải mái. Vậy cho nên activation ở đây đơn giản hiểu là sự kích hoạt với nhà cung cấp mạng di động. Nhưng trong trường hợp này IP chỉ có nhà cung cấp duy nhất là AT&#38;T bởi vậy nếu bạn không là khách hàng của AT&#38;T thì bạn cần phải giả mạo activation (fake activation) bằng cách can thiệp vào hệ thống. Cho nên, đòi hỏi IP phải được JAILBREAK</p>
<p>Làm sao để biết?</p>
<p>Đối với máy OTB (Out of the Box) hoặc mới update, trên màn hình sẽ có dòng chữ “Slide for Emergency”. Kết nối IP với Itunes và synchonize, sau đó ngắt kết nối. Nếu bạn không thể sync được và trên màn hình vẫn là dòng chữ “Slide for emergency” thì bạn cần phải activate. Còn ngược lại, màn hình IP chào đón bạn với dòng chữ “Slide to unlock” thì chúc mừng. Bạn đã được kích hoạt</p>
<p>Unlocking</p>
<p>Unlocking iphone có nghĩa giống như là unlocking SIM trên các máy điện thoại khác. Trên hầu hết các máy điện thoại, quá trình này được thực hiện bằng việc nhập code đặc biệt và bấm nút send/call. Code đặc biệt này đưa máy điện thoại vào chế độ đã unlock –nghĩa là nó sẽ chấp nhận mọi simcard của bất cứ nhà cung cấp mạng di động nào. Và lúc này thì Baseband của phone sẽ dừng việc kiểm tra simcard xem nó có thuộc về nhà cung cấp mặc định nào không.<br />
Quá trình unlocking bao gồm việc xóa bỏ dòng code kiểm tra simcard hoặc sửa lại dòng code đó nhằm mục đích làm cho Baseband chấp nhận simcard</p>
<p>KHÁI NIỆM BOOTLOADER, BASEBAND và FIRMWARE</p>
<p>Để cho đơn giản, trước tiên xin thống nhất với các bạn về quan niệm của tác giả về Bootloader, baseband và firmware như sau:</p>
<p>Firmware : là phần hồn của đứa trẻ tên Iphone<br />
Baseband : là ba lô đựng đồ của đứa trẻ<br />
Bootloader: là bà mẹ</p>
<p>BOOTLOADER:<br />
Version : 3.9 và 4.6</p>
<p>Trong iphone có ít nhất hai loại BOOTLOADER. Một loại gọi là “ARM Core Bootloader”, loại này tương tác với hệ điều hành của iphone. Loại Bootloader mà chúng ta đề cập đến là “Baseband Bootloader”<br />
Như khái niệm dân dã đã thống nhất với các bạn ở trên. Bootloader là bà mẹ, vào phòng của iphone, bật iphone lên, đánh thức nó dậy, đưa ra khỏi giường và chuẩn bị cho nó đến trường. Chức năng chính của bootloader là đảm bảo cho iphone thức giấc trước khi ra khỏi giường, đảm bảo nó ra khỏi giường trước đi tắm, tắm trước khi mặc quần áo, và quần áo phải mặc trước khi ra bến xe bus. Nói có vẻ lằng nhằng, nhưng rõ ràng bà mẹ bootloader này luôn đảm bảo cho đứa con iphone này một trình tự rõ ràng và chính xác. Hay nói cách khác, nó kiểm soát toàn bộ quá trình khởi động, hoạt động của iphone.Nếu không có bootloader thì đứa con iphone sẽ mãi chỉ là đứa bé ngủ với bộ pijama sũng nước trong bồn tắm đợi xe bus đến.<br />
BOOTLOADER đảm bảo cho iphone khởi động (boot) theo đúng trình tự và hoàn thành mọi nhiệm vụ<br />
Giống như mọi người trên thế gian, iphone luôn chỉ có một bà mẹ trong cả cuộc đời của mình. Nếu bạn mua iphone với bootloader phiên bản 3.9 thì bạn sẽ vẫn luôn có bootloader 3.9 cho dù bạn có upgrade bao nhiêu lần đi nữa<br />
Tất nhiên vẫn có những trường hợp mà người ta gọi là mẹ kế. Vậy có thể hiểu có một số người bỏ phiên bản 4.6 để lấy phiên bản 3.9. Có lẽ bạn cũng là một trong số người như vậy.</p>
<p>Tại sao phải quan tâm đến bootloader?</p>
<p>Phiên bản bootloader quyết định phương thức mà bạn bẻ khóa. Bởi lẽ 3.9 là bà mẹ dễ dãi, thoáng tính. Bà ta cho phép chúng ta làm nhiều thứ trong quá trình iphone boot. Qua đó, con dế của bạn rất dễ tiếp cận<br />
Quý bà 4.6 thì khó tính hơn rất nhiều. Bà ta luôn khăng khăng đứa con mình sẽ trở thành Tổng thống trong tương lai và luôn theo dõi, kiểm soát những gì iphone làm hay không thể làm. Ví dụ, 4.6 không cho chúng ta lấy baseband mà bà ta không kiểm soát được<br />
Để thẩm tra baseband (định nghĩa baseband phía dưới), bạn cần secpack (cái này mình không rõ là gì, nếu ai biết xin bổ sung. Mình sẽ cố gắng tìm hiểu sau). Nhưng trong bài viết này tác giả giải thích secpack theo cách dân dã như sau: secpack là những lời dặn dò an toàn mà ông bố, bà mẹ và đứa trẻ được nhắc nhở nếu ông chú của bạn đến đón bạn đến trường ( chỗ này hơi lủng củng, các bạn thông cảm)<br />
Không có secpack, bạn không thể viết baseband đã được hack vào iphone. Hơn nữa, không hack được baseband, bạn không thể sử dụng phương pháp unlock cùng với Ziphone<br />
Nếu bạn thích bootloader 4.6 thì bạn sẽ phải sử dụng phương pháp gọi là soft-update. Phương pháp này cài đặt phần mềm update vào hệ điều hành nhưng không update baseband. Cách này đôi khi được gọi là Hybrid – unlock<br />
Vậy bạn có gì?<br />
Các phương pháp bẻ khóa iphone thường tập trung chủ yếu vào Baseband Bootloader. Có hai phiên bản là 3.9 và 4.6. iphone nguyên bản được bán với Bootloader 3.9. Nếu bạn có firmware 1.1.1 hoặc cũ hơn, nghĩa là bạn sử dụng bootloader 3.9<br />
Nếu iphone của bạn được mua trong năm 2008, có nhiều khả năng nó có bootloader 4.6</p>
<p>BASEBAND<br />
Versions: 03.12.06_G, 03.14.08_G, 04.01.13_G, 04.02.13_G, 04.03.13_G, 04.04.05_G<br />
Baseband là ba lô của đứa trẻ tên iphone. Baseband điều khiển quá trình tương tác giữa các thành phần của iphone và hệ điều hành. Trong hầu hết các loại máy điện thoại, chip baseband tách biệt với hard drive chính và bộ xử lý của máy. Baseband là một trong những thứ mà quý bà Bootloader kiểm tra trong lúc bà ta đánh thức đứa con iphone<br />
Bất cứ khi nào iphone muốn tương tác với cell towers bằng âm thanh hoặc dữ liệu. Nó đều làm việc thông qua baseband. Baseband chịu trách nhiệm đảm bảo simcard hợp lệ và bắt được tín hiệu của nhà cung cấp dịch vụ mạng.<br />
Mỗi khi iphone đến trường, nó đều cần những thứ như sách vở, thước kẻ, máy tính hay là cặp tài liệu. Baseband có tất cả những thứ này. Có thể bạn đã biết, bạn có thể lấy cái ba lô này đi mà đứa trẻ iphone không bị sao cả. Bạn cũng có thể có một baseband không làm việc mà vẫn có một iphone – nhưng mà lúc này thì iphone của bạn giống như là một cái ipod touch<br />
Bạn có thể nghĩ rằng khi bấm số tức là bạn đang thực hiện cuộc gọi. Thực chất không hẳn thế mà là bạn đang tạo ra một chuỗi chỉ thị. Khi bạn bấm phím call, hệ điều hành sẽ đưa các chỉ thị của bạn đến baseband và vô hiệu hóa EDGE, gửi thông điệp đến cell tower rằng nó đang chuẩn bị thực hiện cuộc gọi, cung cấp số điện thoại cần gọi đến và đợi tower truyền lại tín hiệu ( Bận hay đổ chuông). Một khi cuộc gọi được thực thi, baseband sẽ gửi tín hiệu đánh thức microphone và speaker của iphone. Mọi việc mà iphone cần phải làm chỉ là ra lệnh “ Thực hiện cuộc gọi đến số máy này”, bởi lẽ Baseband đã biết rõ tất cả việc cần phải làm. Còn nhiệm vụ của bộ xử lý chỉ là những việc của một người đầy tớ.<br />
Bạn nên nhớ, baseband chịu trách nhiệm về giao tiếp giữa cell towers và hệ điều hành của iphone. Với phiên bản 4.03.13_G, Apple đã thêm một số đoạn mã nhằm đơn giản hóa quá trình xử lý.</p>
<p>FIRMWARE<br />
Versions: 1.0.0, 1.0.1, 1.0.2, 1.1.1, 1.1.2, 1.1.3, 1.1.4<br />
Firmware là phần hồn, là hệ điều hành của đứa trẻ iphone. Hiểu với những khái niệm dân dã chúng ta đã đề cập. Mỗi khi chúng ta bật iphone, bà mẹ bootloader sẽ bắt đầu khởi động phần hồn- hệ điều hành. Nó đảm bảo mọi dich vụ đều được chạy. Nó cũng chuẩn bị và khoác ba lô Baseband lên vai cho đứa trẻ, sau đó thì đưa đứa bé đến trường<br />
Firmware của iphone rất linh hoạt, nó bao gồm phần cốt lõi của iphone, ứng dụng Springboard, ứng dụng mainpage iphone, khả năng điều khiển ăng ten Wifi, hay điều khiển các Web pages. Cùng với khả năng của firmware, Apple có thể thay đổi rất nhiều thứ.</p>
<p>(sưu tầm)</p>

<content:encoded><![CDATA[<div class='snap_preview'><p style="margin:0 0 10px;padding:0;">Let’s continue from where we left off in the <a href="http://deviceconvergence.wordpress.com/2009/09/11/st-ericsson-diverse-offering/" target="_blank">previous post</a>, with an analysis of ST-Ericsson’s portfolio.</p>
<p style="margin:0 0 10px;padding:0;"><strong>Innovation</strong></p>
<p style="margin:0 0 10px;padding:0;">Even as it juggles the enormous task of integrating various teams, ST-Ericsson needs to be commended for continuing to deliver innovative products. Its Aero4228 solution, an RF transceiver for HSPA/EDGE, eliminates the need for expensive external filter components, thus saving money and space in the end design. The company also claims some industry firsts for sampling connectivity chips using 45-nm CMOS technology — this will be discussed in more detail below.</p>
<p style="margin:0 0 10px;padding:0;"><strong>Connectivity</strong></p>
<p style="margin:0 0 10px;padding:0;">Combo chips are gaining momentum thanks to the cost and space savings they provide. As early as this January, at the consumer electronics trade show CES 2009, ST-Ericsson talked up combo chips as a big part of its strategy and roadmap. Prior to this month, the company had little to offer in the area of combo chips for connectivity — there was just the single-chip BT/FM part. The JV recently <a href="http://www.stericsson.com/press_releases/Combo_solutions.jsp" target="_blank">announced</a> two single-chip parts: CG2900 and CW1100 using 45-nm process.</p>
<p style="margin:0 0 10px;padding:0;"><!--more--></p>
<p style="margin:0 0 10px;padding:0;">CG2900 is a single-chip GPS/BT/FM solution. It is not the first such combo chip: BCM2075 from Broadcom and BlueCore BC7830 from CSR offer similar functionality. However, ST-Ericsson is not just playing catch-up, as its sollution is the first to use 45-nm process technology. The power- and space-saving advantages of the CG2900 are due, in part, to its being a 45-nm part. The BCM2075, in contrast, is based on 65-nm. The CG2900 will not be in production until the second half of 2010, whereas competing parts should be seen in phones later this year. If the CG2900’s performance matches or exceeds the competition, the power and space savings will likely lead to an increased uptake of this part. This effort will further increase attach rates of GPS and BT.</p>
<p style="margin:0 0 10px;padding:0;">CS1100 is a single-chip 45-nm WLAN part, another industry first. CS1100 claims to be an “ultra-low power IEEE 802.11n WLAN device.” The higher power consumption has been detrimental to attach rates of 802.11n in mobile devices. If the promised performance comes to fruition, it would mean a major breakthrough for ST-Ericsson. Again competitors like Broadcom have similar products in production albeit at 65-nm.</p>
<p style="margin:0 0 10px;padding:0;">BT 3.0 achieves its high speed by riding on a WLAN PHY layer, inherently assuming that a WLAN part would be present in the device. Whether or not co-existence with a WLAN part is the best strategy for BT going forward is debatable, and one part of the discussion can be found <a style="color:#333333;font-weight:bold;text-decoration:none;" href="http://www.incisor.tv/stories/2009/09/only-alternative-bluetooth-and-ultra.html" target="_blank">here</a>. There is no BT/GPS/WLAN/FM single-chip solution from anyone yet. Any design seeking to add all four connectivity options, at the time of writing, needs at least two discrete parts, just as ST-Ericsson recommends using CG2900 and CS1100 together. However, when a design chooses to provide just BT/WLAN/FM, competitors will steal design wins with a single-part solution. It appears that by not putting out a BT/WLAN/FM part, ST-Ericsson is betting on increasing attach rates for GPS.</p>
<p style="margin:0 0 10px;padding:0;">The series ends tomorrow with a discussion of ST-Ericsson’s strategy and our thoughts on the outlook for the company.</p>

<content:encoded><![CDATA[<div class='snap_preview'><p style="margin:0 0 10px;padding:0;">Following <a href="http://deviceconvergence.wordpress.com/2009/09/10/st-ericsson-a-new-force-in-wireless-semiconductors/" target="_blank">yesterday’s introduction</a> to ST-Ericsson as a company to be watched, today we take a look at its portfolio and consider some growth prospects.</p>
<p style="margin:0 0 10px;padding:0;"><strong>Portfolio</strong></p>
<p style="margin:0 0 10px;padding:0;">Building on the strengths of EMP, the JV offers platforms for entry level, feature and smart phones. In addition the JV offers individual components to be used in other platforms. The strategy is evident in their claim, “A total solution or its individual parts”.</p>
<p style="margin:0 0 10px;padding:0;"><!--more--></p>
<p style="margin:0 0 10px;padding:0;">The product portfolio needs to be streamlined. Consolidating operations from such diverse, overlapping portfolios efficiently was a daunting task from the get-go. The savings and synergies, where they exist, have to be found while continuing to support all products at various customers in the short term, as was done prior to the JV. The challenge will be to choose the best solution where there are overlaps. After electing what should thrive, the company needs to convince existing customers to move to such offerings.</p>
<p style="margin:0 0 10px;padding:0;"><strong>Just Wireless Handsets</strong></p>
<p style="margin:0 0 10px;padding:0;">While forming this JV, the parents retained access to some technologies that were not exclusive to mobile handsets. For example, STM continues to have access to Nomadik application processor, and recently announced Cartesio+, a single-chip solution that combines GPS and an application processor for media processing; NXP continues to be a big player in NFC and AM/FM tuners; and Ericsson recently launched a mobile broadband module specifically designed for netbooks. Thanks to such plays as STM, NXP held on to the top two positions in automotive infotainment IC space. STM continues to be a major force in accelerometers and gyroscopes, and it reminds us of its value-add for mobile phones with the recent announcement of a battery monitoring IC.</p>
<p style="margin:0 0 10px;padding:0;"><strong>Baseband</strong></p>
<p style="margin:0 0 10px;padding:0;">Owing to their shared lineage, ST-Ericsson will become the dominant supplier to Sony-Ericsson. In addition to design steals at Sony-Ericsson, ST-Ericsson stands to gain market share and revenue from TI due to the latter’s winding down of merchant baseband business. ST-Ericsson is one of just four companies with more than 5% baseband market share. Earlier, Nokia added ST-Ericsson as another 3G baseband supplier.</p>
<p style="margin:0 0 10px;padding:0;">ST-Ericsson has a portfolio that covers 2G, 2.5G, and 3G technologies and a road map that includes LTE. While the JV has good momentum in high-end phones and feature phones, at the low end it has to compete with the likes of a very aggressive MediaTek.</p>
<p style="margin:0 0 10px;padding:0;">Major handset makers are ramping up their smartphone offerings. As an example, LG recently announced plans to release a total of 13 Windows Mobile-based smartphones by the end of 2010. Courtesy of the strong relationship between EMP and LG, ST-Ericsson should have a big part of this business.</p>
<p style="margin:0 0 10px;padding:0;">Owing to these factors, ST-Ericsson will likely continue to gain baseband market share.</p>
<p style="margin:0 0 10px;padding:0;"><strong>Application Processor</strong></p>
<p style="margin:0 0 10px;padding:0;">ST-Ericsson stood at a distant fourth position, taking <a style="color:#333333;font-weight:bold;text-decoration:none;" href="http://www.fwdconcepts.com/dsp62409.htm" target="_blank">9.4%</a> of the standalone application processor (AP) revenue in 2008. The JV chose STM’s Nomadik application processor over NXP’s Nexperia and EMP’s tradition of sourcing from TI. ST-Ericsson entered into a pact with Nokia to provide APs using ARM’s latest offering, Cortex-A9, for 3G handsets and smartphones based on the Symbian S60 platform.</p>
<p style="margin:0 0 10px;padding:0;">Many of the JV’s platform offerings are built around a Nomadik + baseband communication processor. Given this increased opportunity for Nomadik, ST-Ericsson’s standing in the AP market should improve, partly at the expense of TI’s OMAP processors.</p>
<p style="margin:0 0 10px;padding:0;">Tomorrow’s post continues with the portfolio analysis.</p>
<p style="margin:0 0 10px;padding:0;">[Originally for <a style="color:#004477;text-decoration:underline;margin:0;padding:0;" href="http://www.sramanamitra.com/" target="_blank">Sramana Mitra on Strategy</a>.

<content:encoded><![CDATA[<div class='snap_preview'><p>Questo post è principalmente u<strong>no sfogo, un appello, un modo egoista</strong> per mettere in luce il <strong>problema che sto avendo con il mio iPhone 3G</strong> e che spero qualcuno possa aiutarmi a risolvere.<br />
Purtroppo il mio iPhone 3G è uno dei pochi (o tanti??) melafonini ad avere <strong>problemi con il WiFi</strong> dopo l&#8217;aggiornamento al firmware 3.0</p>
<p>Ad oggi sono ormai 15 giorni (si, è vero&#8230; ho aspettato tanto a fare l&#8217;aggiornamento alla 3.0) che tento di trovare una soluzione al problema del WiFi non funzionante, ma a quanto si legge in giro sui forum e sui blog, sembra che la baseband venga in qualche modo corrotta e che il ripristino del firmware non sovrascriva in nessun modo questa parte di O.S. (che ha in carico la gestione radio del sistema: WiFi, fonia, bluetooth e GPS). In compenso il bluetooth e il GPS funzionano egregiamente&#8230; e quando eseguo l&#8217;unlock funziona correttamente anche la parte della fonia incluso la connessione dati.</p>
<p>Ciò è strano visto che tutte le persone che hanno avuto problemi con il WiFi dopo l&#8217;upgrade al firmware 3.0 hanno anche avuto svariati problemi al GPS e al bluetooth.</p>
<p>Volendo entrare nel dettaglio: i problemi che si sono presentati più spesso agli utenti sono questi tre:</p>
<ul>
<li><strong>grey WiFi</strong> &#8211; il WiFi è completamente disabilitato. Il tasto d&#8217;attiviazione risulta grigio e non cliccabile. L&#8217;iPhone non presenta nessun mac address per il WiFi e il bluetooth</li>
<li><strong>Ricezione WiFi debole</strong> &#8211; il WiFi funziona a tratti e si disconnette dopo pochi minuti di utilizzo.</li>
<li><strong>WiFi non rileva reti</strong> &#8211;  il WiFi è attivabile, ma non rileva reti, anche a distanza ravvicinata con il router</li>
</ul>
<p>Putroppo io ricado nella terza macro-categoria, <strong>ovvero nessuna rete viene rilevata, anche dopo aver effettuato il Reset Network Setting</strong> ovvero la soluzione proposta da Apple sul forum di supporto.</p>
<p>Inizialmente (nei primi 3 giorni dall&#8217;upgrade al firmware 3.0) il mio iPhone <strong>rilevava le reti ma perdeva il segnale</strong> o comunque è sempre molto debole, ricadevo in modo chiaro nella seconda categoria di problemi. Sul Discussions.apple.com <a href="http://discussions.apple.com/message.jspa?messageID=9740629#9740629" target="_self"><strong>ho anche trovato un modo strano, curioso, ma incredibilmente funzionante per risolvere tale problema</strong></a> ovvero:</p>
<p><em>1&#62; restart yo0ur phone ! as soon as it reboots get into wifi settings and connect to ur network ! (u can find ur network everytime u restart)<br />
2&#62; now connect to it &#38; then w8 till the wifi logo appers in the top !<br />
3&#62; quicky enter apple app store &#38; download a free app !<br />
4&#62; after then app has been downloaded &#38; installed ! go into ur settings&#62;general&#62;reset&#62;reset your network settings! ( be sure to do all of the above steps &#38; also be sure that while u reset ur connected to wifi &#38; the logo appers on the top)<br />
5&#62; after ur phone resets &#38; reboots go into ur wifi setting &#38; u will be able to connect &#38; stay connect to ur network without any problem !</em></p>
<p><strong>Seguendo questa anomala sequenza di passaggi il mio iPhone ha iniziato a rilevare correttamente le reti mantenendo la potenza di segnale in modo identico al firmware 2.2!</strong> Purtroppo però dopo soli 2 giorni di corretto funzionamento (alla ricezione di un MMS &#8230;) il WiFi ha smesso di nuovo di funzionare, questa volta in modo definitivo, come descritto sopra (le reti non vengono rilevate).</p>
<p>Ho cercato aiuto chiedendo dei metodi di debug e risoluzione a MuscleNerd (membro e portavoce del DevTeam), ma purtroppo tutti gli strumenti sviluppati dal DevTeam non sono ancora stati portati su 3.0, vedi <a title="SWiFi" href="http://wikee.iphwn.org/sgold_bootrom:fixwifi" target="_self"><strong>SWiFi</strong></a> e il WiFi tables dumper.</p>
<p>A questo punto non mi resta che sperare nel firmware 3.1, ma purtroppo la situazione non è molto rosea: il prossimo JailBreak che il DevTeam proporrà per il firmware 3.1 sarà basato sull&#8217;<strong>utilizzo di un Custom 3.1</strong> firmware (generato con il prossimo PwnageTool) <strong>con baseband 04.26.08</strong> ovvero quella del 3.0; questo perchè la nuova baseband del 3.1 non è vulnerabile agli exploit attualmente utilizzati da UltraSn0w (software di unlock per la parte telefonica di cui io ho sicuramente bisogno in quanto il mio iPhone ma è italiano&#8230;) e quindi non è ad oggi possibile effettuare un jailbreak del 3.1 nativo e tanto meno l&#8217;unlock. Se però la mia baseband 04.26.08 è realmente corrotta, non sovrascrivibile, non downgradabile (<strong>il mio bootloader è purtroppo il 5.9 e</strong> <strong>nemmeno Fuzzyband Downgrader mi può aiutare</strong>) allora difficilmente risolverò il mio problema con il WiFi installando un firmware che ha la stessa versione di baseband.</p>
<p>E per oggi questo è tutto. Chissà che un guru possa leggere ste righe e magari possa in qualche modo aiutarmi.</p>
<p>La speranza è l&#8217;ultima a morire e, come dice spesso un mio caro collega, scusate lo sfogo.</p>
<p>ciao<br />

<description><![CDATA[  Smartphones are poised to be the fastest growing handset segment in the coming years, rising from ]]></description>
<content:encoded><![CDATA[<div class='snap_preview'><p> <br />
Smartphones are poised to be the fastest growing handset segment in the coming years, rising from 14% of global handset shipments in 2008 (Ref 1) to a projected 32% in 2010 (Ref 2).</p>
<p>Further, smartphones command higher ASPs (average selling price) on the order of US$350 (2008)  signaling higher revenue and profitability potential for handset OEMs. This has heightened the intensity of competition among handset makers.</p>
<p>Historically, handsets have evolved more as ‘fat modems’ where application processing and modem communication were all handled on the same chip. On the other hand, application centric devices such as PCs, gaming devices etc. evolved as standalone devices based on discrete applications processors. Connectivity was added on via discrete connectivity modules.</p>
<p style="text-align:left;">While data speed does impact user experience, application and related services offer many dimensions to differentiate personalization and user experience, thus leading to higher ARPU over voice centric services.</p>
<p>The two worlds are set to collide to create converged devices with vast possibilities (Refs 3 and 4). It also means non-traditional wireless players whose core competency is more on the applications side will enter the fray. For example, Intel is pushing its application processor, Atom, from Netbooks down into Smartphones (Ref. 3). On the other hand, Qualcomm has just announced it is targeting its integrated application and baseband processor, Snapdragon, at Smartbooks (Ref 4). </p>
<p><strong>CRITICAL QUESTION  – DISCRETE vs. INTEGRATED PROCESSORS?</strong></p>
<p>The handset designer is now confronted with a daunting choice – the use of a discrete applications processor in conjunction with a discrete baseband processor versus an integrated SoC that combines an applications processor with a baseband processor in a single chip.</p>
<p>Product management and handset designers need to evaluate the trade-offs in reaching an appropriate decision. Here are some key trade-offs that influence the decision process:</p>

<div id="attachment_165" class="wp-caption aligncenter" style="width: 460px"><img class="size-full wp-image-165" title="Discrete vs. Integrated Smartphone Components" src="http://emblazeworld.wordpress.com/files/2009/08/discrete-vs-integrated-smartphone-components3.png" alt="Discrete vs. Integrated Smartphone Components" width="450" height="575" /><p class="wp-caption-text">Discrete vs. Integrated Smartphone Components</p></div>
</div>
<p style="text-align:left;"><strong>Neither is a silver bullet.</strong></p>
<p style="text-align:left;">Both have a rightful place and will jostle with each other to dominate this growing segment.</p>
<p style="text-align:left;">The choice however can have significant implications on product and business competitiveness via such dimensions as system cost, time-to-market, power consumption, flexibility to spin out devices for different communication standards, performance maximization, harmonization of user experience, device form factor (via PCB size &#38; component count) and component supply chain management.</p>

<content:encoded><![CDATA[<div class='snap_preview'><p>If you are a developer, the iPhone sdk / os 3.1 beta 2 is now available to you from apple. (Build 7C106c). They are available on the iPhone Dev Center for download. This update is for beta testing purposes only. If you feel a need to have it, just google, im sure it is out there. iPhone 3G S and 3G users with ultrasn0w or purplesn0w do not update to 3.1 when it comes out ( or the betas) as it will permanently update your baseband.</p>
