    LMAO!! I remeber these same excuses back when 1.0.2 and beyond came about... I really dont understand how some1 can ACCIDENTLY upgrade their firmware to a newer version, and everyone use the same reason, I accidently upgraded or my brother\sister upgraded... LMAO! It impossible to accidently upgrade when all you have to do is accidently disconnect your deivce while the firmware is downloading throug iTunes... OR pay attention to the buttons to be pressed when prompted about an update. But even if the button is pressed to upgrade, iTunes stil has to prepare itself for the flash, DISCONNECT during preparation. I just dont get it.

    Back to unlocking it... I guess you have to wait for the unlock from dev team, or search to find a way to downgrade, I hear BigBoss has an way to do this.

    Usually, when I accidentally upgraded the firmware, I try to download an older firmware (1.1.4) and restore it manually by clicking Restore in iTunes while holding shift, then choosing the firmware of your choice.

    I recently found a website that shows how to downgrade from 2.0 to 1.1.4

    Downgrading 2.0 to 1.1.4

    Tell me if you have any other questions.

    Hello,

    I did the same thing. Just got trigger happy with the mouse and updated and tried all kinds of things to unlock it, but no success.

    I tried restoring the phone to 1.1.4, but that didn't work either.

    Any new suggestions???

    You need to downgrade on your baseband.
