I have a buddy that I am buying a few phones for, and my task is to unlock these phones and ship them to him. I am very concerned about bricking the phones (since they are not mine). I would have to assume at this point that most new phones purchased from the apple store or AT&T are installed with the 1.1.1 firmware. Is it possible to go from the virgin 1.1.1 firmware to 1.02 unlocked? Any help in shedding some light on this would be great.
