iPhone 3G 2.2 Firmware Sim Unlock (Gevey SIM, Turbo SIM) Experiences
Update : Dev Team confirmed the release date for Software Unlock. Please steer away from x-sim unlock techniques. 2.11.07 is the best baseband for now. 2.28 baseband users : solution pending.
Apple’s iPhone 2.2 Firmware certainly sports some cool new features but is it worth taking the risk and updating given the fact that it disrupts the ONLY available unlocking technique ( Sim Unlock ) ?
I have some iPhone 3G’s (bought from Canada) at my disposal and I first updated one of my iPhone 3Gs directly to firmware version 2.2 since I have an ATT account and it clearly breaks the Gevey SIM unlock hack due to Apple sneaking in a Baseband update with the new firmware release.
Take two, with iPhone Devs taking time off over the weekend to release Jailbreak techniques for the newly released firmware v2.2 , I Pwned one of my other iPhone 3G’s with QuickPwn when at firmware version 2.1 and then used Pwnage tool 2.2 to create this Custom Firmware v2.2 without the baseband update. Technically Gevey SIM should survive this update and while it did survive, I have been experiencing some flaky service issues. Not sure if it is with the Gevey SIM (I have more, so I can try with another Gevey SIM).
The power user I am, I should be able to narrow down the cause of an otherwise fantastic interim unlock for iPhone 3G v2.2 till iPhone Devs post a software unlock (hopefully SOON)!
Status : Please hold your horses and WAIT if you are relying on Gevey SIM for unlocking your iPhone 3G. This post will act as a placeholder for Gevey SIM and iPhone 3G, hence it will be frequently updated.
Interim Status :
EDGE and 3G Data works just fine
3G signal not the best, EDGE best
No Voice issues so far
iTunes Sync works just fine
