I have a iPhone 3gs that was unlocked and jailbroken. My girlfriend updated the phone, and now it is in activation mode and wont read the SIM card that was in it. How do I restore the phone so that it works again ?

    i think that you need to re-install it, because whenever i try to update my jailbroken iPod Touch 4G, it does not work :/
