    Get urself a custom firmware that's 3.1.2 that doesn't have a baseband upgrade or does because they're both unlockable.

    Then go to ih8sn0w.com and download ireb.

    Use it to put ur 3g into dfu mode (white screen)

    and then just shift restore

    use ultrasn0w for 4.28
    or blacksn0w for 5.11
    to unlock
