    Default Unlock iPhone 4

    So i have an officially unlocked iPhone from italy and my aunt is giving me hers (AT&T) when her white IP4 arrives.

    Is there a way to unlock it. Not sure of the baseband - im in India and she in the states.
    I do know its OS 4.2.1

    Can i unlock it if yes - How

    if No whats the latest update on the unlock for IP4. I read somewhere on this forum we can unlock 4.1 can i downgrade to an unlockable OS

    That will depend on how you performed the update from 4.0 to 4.2.1. If you used a custom firmware and preserved baseband, you can unlock, but if you used an original firmware, the baseband was updated and you can no longer unlock with ultrasn0w. Unfortunately, there's no way to downgrade the baseband on the iPhone4. The only solution would be the gevey sim, it is not the ideal solution, but it works. Google Gevey SIM iphone 4 for more info.
