    My sister has a 1.0.1 firmware on the iphone 2G.

    I want to upgrade her to 3.0.1
    What is the best way to do that?

    Should I just do a restore on my itunes? and then go through QuickPwn and do everything normally?

    Thanks

    1.0.1! :eek: :eek:

    Yeah, I think were it a later firmware than that, it would even stay unlocked, but in this case you'll have to unlock it again. Very worse thing that can happen is that you'd have to DFU it to unlock it (not at all hard, and it's how Redsn0w works now anyway).

    Back up the phone with iTunes before you start. Right click on the phone in the left-hand menu.

    You can restore from the backup once RedSn0w is done.
