    Default [DOWNGRADE] Downgrade iPhone 3G 3.0 to 2.2.1

    I DO NOT take any credit for this.
    I read this on another forum and was written by a user called delldude1989 who found this solution. The solution to downgrade from iPhone 3.0 to iPhone 2.2.1 is as follows:

    1. Attempt a restore of 2.2.1 in DFU Mode

    2. Get the iTunes error message.

    3. Reset device

    4. Launch QuickPwn

    5. Press next and get past the first 3 steps.

    6. Bam, phone is fixed.

    I have not tested this myself know let me know if it works or not

    Thank you for testing it and confirming it works.
    Can you let me know if all features work in 2.2.1 with the 04.20.01 baseband?
    SMS, 3G etc

    Guys, I've read the 3.0 release notes but they aren't clear to me.... are you able to use this beta firmware fully without having a dev account or does it need some sort of dev activation? I'm considering purchasing the SDK to get it early if it does.

    Hi
    Im not sure that updating to 3.0 & ending up on 04.20.01 BB was or is a wise thing to do, especially if you wanted to unlock on a non official network in the future. Because I wouldn't think its posable to downgrade the BB backwards

    It's just accident but lucky mine one is officially unlocked then no problem. Anyway it is not recommended for iPhone using yellowsnow to unlocked.

    No joy here. Quickpwn does not even detect the phone.

    Cant get it out of DFU mode either. Seems like I'm screwed!
