    My Iphone 3G/8GB with 4.1OS will not power off, I tried several things to power off or put in PDU without any success. It happened every since my wife accidentally upgraded to 4.1 OS through Itune.
    If I need to down grade to 3.1OS or any OS for that matter I will have to turn off to proceed with any steps to downgrade. any help with this I will appreciate.

    Hard reset will turn it off if your iphone is frozen. Turning off your device does not let you downgrade, you have to put it in DFU mode which also looks like it is OFF.
