Have got an old 2G that is jailbroken and unlocked. Since I now have a 3GS I wanted to give the 2G to my sister and then I choosed the iPhone option to reset and restore it. It seemed to work ok but now it stopped when trying to reeboot. All I see is the Apple logo and the spinning wheel (not moving) occasionally the spinning wheel disappears and comes back and spins for 1 second. I can't turn it off/on and have tried to get it into DFU even though it's on. Nothing happens. Somehow I can access the iPhone through my Mac with USB and restore it somehow without DFU/iTunes?
