I seem to have just run into some very bad luck. I'm selling my 4th gen 20GB iPod on eBay and the auction is due to end today. So I tried to turn on my iPod just now to reset it, but it won't turn on. I press all of the buttons and nothing happens. I thought the battery might be dead (even though it was about half full last night when the iPod was working fine), so I tried plugging it in, but nothing happens. Since last night, my iPod has just been sitting on my desk. Is my iPod dead?
