Anyone else had the problem where you can't hard-power-off your iPod touch? I hold the front button and power button, and move the slider to confirm turning it off, and it turns off for about a second and then turns back on starting with the apple logo. Also, my songs are randomly pausing, and then I have to press play again. It just started happening last night, and I've only had the thing for a week, so I guess I should exchange it (if they let me), but was wondering if there are any tricks I could try instead. I'd hate to lose the songs and shows I just bought if I have to return/exchange it.
