    Did it for an American friend with a 3Gs on 5.14.02 and works perfect. People using vista or windows7 HAVE TO:

    – run Redsn0w in windows XP compatibility mode (service pack2 for me)

    – run Redsn0w as an administrator

    otherwise your phone WILL get stuck!

    This happened to me the first time I tried (ran as admin but forgot compat. mode) resolved this by draining the batt. completely and then start the jailbreak again.

    Worked like a charm, thanks to everyone I got info from and the devteam who made this possible.

    I was stuck on 3Gs 05.14. I updated to 06.15, worked fine. Then installed Ultrasn0w 1.2, worked fine. Entered my Finnish SIM (Operator:Elisa) and the phone says ‘Different SIM detected, Please connect to iTunes. Only emergency calls’. And iTunes says SIM seems to be unsupported …

    What went wrong !?

    I take that back. After restoring it works on any network. Need to boot tethered everytime my phone goes off. Just need to watch my battery life. Thanks!

    Hi, this has the same outcome as the previous version of redsn0w. When i get to the final process and reboot I see the apple symbol and this doesnt change.

    All iPhone 3G jailbroken iPhone 3G and can be opened, even if the new iPhone bootrom. bootrom new iPhone is the same band, so you can still use the same opening, but apparently has a different nojailbreak bootrom so it is now.
