My iPod Touch (32gb July 08) has started to think that the off button is always being held down and the off button has ceased to function normally. So it will turn itself on then off and keep repeating this process till the battery runs out. If I plug it in to the mains power it will turn on OK but as soon as I unplug it and it remains inactive for about five seconds it will turn off and the whole loop will start again. Its still in waranty but I am currently abroard and cant get to an apple store any suggestions?
