G'day guys, I need your help with my iPod, I was listening to it the other day with about three quarters of battery power left then all of a sudden it just stopped. On the screen it is displaying a battery with exclamation mark. I have tried resetting it by pressing menu and play/pause simultaneously, switching the iPod on and off but nothing seems to be working. What can I do? Is my iPod broken? I've got over 400 songs on there....what do I do? Help me please.
