I got this appear on my iPod Touch lock screen. It had been on charge for a couple of hours and suddenly popped up. Any ideas why all of a sudden? The charger is not a new one and no one else in the family has had a problem.
Hmm that's weird. I usually get that when I connect my iPod to a car stereo via the USB connect.. Has it happened more than once? If not then it was probably just a weird glitch.
