    Hello all:

    I want to upgrade my jailbroken and unlocked 3G from 2.2 firmware to 3.0. does anyone know that this will mess up my phone and it becomes locked again? I like the new 3.0 because some of the new app softwares only run with a 3.0 firmware. Please let me know if anyone have any experience with this process of upgrading. Thanks in a million.

    Just update to 3.0, then rejailbreak and use ultrasn0w to unlock.

    add repo666.ultrasn0w.com
