Updating iphone 3g to 2 2

Apple had released i Phone firmware 2.2.1 back in Jan which included some minor bugs and improvements.However Dev Team had warned against updating to firmware 2.2.1 without preserving the baseband if i Phone 3G users wanted to unlock their i Phone as it also included a baseband update () which breaks the "injection hole" that they had used in their application yellowsn0w to modify the firmware which had helped to successfully unlock i Phone 3G.Options if you have already Upgraded to i Phone Firmware 2.2.1: So if you have upgraded your jailbroken and unlocked i Phone to firmware 2.2.1 (or just about a new i Phone which came pre-installed with firmware 2.2.1), then you are left with the following options depending on your version of the i Phone: 1st gen i Phone: Since the update does not touch the baseband of the 1st gen i Phone your unlock will remain in place.However to jailbreak your 1st gen i Phone you will need to wait for the dev team to release updated versions of Pwnage Tool and Quick Pwn tools which will let you jailbreak your 1st gen i Phone running firmware 2.2.1.They released the updated version of their Pwnage Tool 2.2.5 which allows users to update their i Phone 3G to firmware 2.2.1 and also jailbreak it but at the same time preserve the baseband so they can unlock their i Phone.

So i Phone 3G users should use Quick Pwn 2.2.5-2 if you DON' T care about unlocking and want to ONLY jailbreak your i Phone 3G.

Last month, the i Phone hacking community had released a tool called p Hase Ban Downgrader to help i Phone 3G users who had accidentally upgraded to i Phone OS 2.2.1 without preserving their baseband to downgrade baseband from to .

However, the tool had two limitations, it worked with only bootloader version 5.08 and it was only meant for those who were technically inclined as it required some command line work.

The latest versions of their i Phone hacking tools are Pwnage Tool 2.2.5 and Quick Pwn 2.2.5. One of the most common problems after Apple releases its the latest firmware update for the i Phone is that some users who have jailbroken their i Phone end up losing the jailbreak and all the jailbreak i Phone apps and if they have unlocked their i Phone end up locking their i Phone if they accidentally upgrade to the latest firmware update.

So when Apple released i Phone firmware 2.2.1 on Tuesday, quite a few readers ended up accidentally upgrading their i Phones to the latest firmware update despite the warning from the i Phone Dev team.
