Using QuickPwn does not update the firmware itself, this tool is designed to ‘Pwn’ (the ability to install future custom non-Apple firmwares) , ‘Jailbreak’ and install Installer and/or Cydia on a given device. If your device is running 2.0.1 and you QuickPwn it, it’ll still be running 2.0.1, although it will now be Pwned and Jailbroken. It will also activate (not unlock) devices that are being used outside of their intended territories and cannot be activated using iTunes.
If you want to update to 2.0.2 then use the normal iTunes update to get to 2.0.2 and then use QuickPwn to Pwn, Jailbreak and Activate, remember that the 2.0.2 update includes a baseband update for the 3G iPhone, so depending what your long term intentions are for the phone, update wisely, of course in the upcoming PwnageTool application you’ll be able to create a custom ipsw without the baseband update enabled.
It is available for download here, but beware this is still beta software. It is fairly self explanatory and easy to use. You’ll still see a command-line window popping up when the actual QuickPwn process takes place, but the device and ipsw selection is handled by the GUI.
Disable airplane mode before installing Prior to installing the iPhone OS 2.0.1 update, make sure that Airplane mode is not enabled on your iPhone. Having Airplane mode turned on can result in a non-functional phone when the update is applied. You may receive the error message:
“Information for activation cannot be obtained from the iPhone”
Fortunately, you can disable Airplane mode from the emergency screen if your iPhone is put into an inactivated state by a problematic update.
“iTunes could not update the carrier settings on your iPhone” Several users are receiving the error message “iTunes could not update the carrier settings on your iPhone. An unknown error occurred (OxE80000001).”
If this error occurs, try clicking the “Restore” button in iTunes rather than “Update.”
Now older IPhone users users can upgrade to firmware 2.0 and IPhone 3G users have a possibility to have jailbreaked IPhones. That is because PwnageTool 2.0 is released today. Download links are: mirror1, mirror2, mirror3.
Just a reminder: this tool jailbreaks and unlocks older iPhones, and jailbreaks iPhone 3Gs and iPod Touches. No unlock for Iphone 3G yet. The supported firmware is 2.0 only. Platform is Mac OS.
If you get Error 1600 from iTunes (or if you see in your log a failure to repare x12220000_4_Recovery.ipsw), try: mkdir “~/Library/iTunes/Device Support” ; if that directory already exists, remove any files in it. Then re-run PwnageTool.
Reminder: as of right now, there are no apps out for 2.0. Over the next few days some will come out. So do not update yet if you have some favorite 1.1.x apps you are using! 2.0 will not run 1.1.4 apps
Portelligent and Semiconductor Insights published a document describing interals of IPhone 3G. Techonline described the details. (Previous IPhone 3G internals photos can be viewed here)
Commuunications (3G/GSM) are on Infineon chips. One for GSM/GPRS/EDGE, another for WCDMA/HSDPA (3G). GPS module is not SiRF as we all thought. Apple uses PMB 2525 Hammerhead II. The Hammerhead II integrates an assisted-GPS (A-GPS) baseband processor with a low-noise GPS RF front end and multi-path mitigation to avoid large errors in urban environments.
DevTeam recently published a video of working PwnageTool 2.0 - for unlocking, activating and jailbreaking IPhne fimware, that will work with the new firmware 2.0.
"Many many hours have gone into this and now it should be as easy enough for your grandmother to use. We’ve added lots of new features, including 2.0 support, spotlight file indexing of .ipsws, canned websearches, installer custom configuration, custom root partitions and various other things that you’ll see on the release. Release date is soon although not this weekend. So check out the video, hopefully it will hold you off until we release."
PwnageTool works with 2.0 upgraded 1st gen (!) iPhones if they are activated or not.
JamVM is a new Java Virtual Machine which conforms to the JVM specification version 2 (blue book). In comparison to most other VM's (free and commercial) it is extremely small, with a stripped executable on PowerPC of only ~200K, and Intel 180K. However, unlike other small VMs (e.g. KVM) it is designed to support the full specification, and includes support for object finalisation, Soft/Weak/Phantom References, class-unloading, the Java Native Interface (JNI) and the Reflection API.JamVM currently only includes an interpreter (keeps it small). However, the interpreter is highly optimised, and performance is on par with a simple JIT. As most of the code is written in C it is easy to port to new architectures.
