I left my iPod playing until the battery went dead last night and now when I plug it in using the USB cable, I get an endless reboot (just as the don't-unplug-icon appears, it starts all over again). Searching, I found a somewhat similar description but this was apparently related to some sort of tinkering/using an unauthorized recharging device. All I did was leave it until it switched off by itself - something I've rarely if ever done before. I've tried holding down the menu switch in order to charge without connecting but the same thing happens. Help?
EDIT: I have succeeded in getting it to stop the loop (though no idea why). I connected with the hold switch on which made it go 'cleared' every time it rebooted, removed the hold switch in mid-boot and then it booted in normal connected status.
