My ipod naaIno is stuck in the lock position, my hold switch will not turn off even when I move it. I have tried restoring it and resetting it and it still comes back on in the hold/locked postion. It will only play when placed on a docking station and then I cant scroll to pick songs, I can only go to next song using buttons on docking station.
