Okay guys, I know this is killin all the jailbroken iphoners with Their updated firmware, This is how you get back to 2.2, Or 2.1:

follow these steps to downgrade from iPhone firmware 2.2.1 to firmware 2.2 or 2.1:

* Connect your iPhone to your Mac or PC and select your iPhone from the list of devices in iTunes. If things had gone horribly wrong while hacking your iPhone and iTunes does not detect your iPhone then you will need to put it in DFU (Device Firmware Upgrade) mode.

o You can follow these steps to put your iPhone in DFU mode (this is required only if iTunes does not recognize your iPhone):
+ Connect your iPhone to your computer.
+ Turn iPhone off.
+ Hold power and home together for 10 seconds (exactly).
+ Release power but keep holding home until the computers beeps (observed on a PC) as a USB device is recognized.
+ A few seconds later iTunes should detect your iPhone.

* In the Summary Tab, Hold down Option and press the "Restore" button. If you are using Windows hold down Shift and press the Restore button. (This is an important step as just pressing the "Restore" button will result in restoring your iPhone with the latest firmware which is firmware 2.2.1 currently, by holding down Option in case of Mac or Shift in case of Windows, allows you choose the firmware file that you want to downgrade to.)


After the restore, flip on the QUICKPWN and your back in business

Does this work for iphone 3g? Or just for iphone 2g? Ok u can get it rejailbroken but the baseband still remands the same witch means your sim card with not work..

I have a 2G, i dont know if it will work for the 3G. someone daring?

[QuickPWN]

iPhone 3G users: Do not upgrade to firmware 2.2.1 if you want to unlock your iPhone 3G because it permanently updates your baseband and you can't use yellowsn0w iPhone 3G unlock with the newest baseband.
