Is it normal for an iPod to freeze? Once I put my video iPod on lock and after that it just froze. It wouldn't get out of lock it just......froze. I took it to my brother and it started working normally again. Last night it did it again. I showed it to my brother and it wasn't turning on and the batteries were fully charged so he plugged it into a charger and then it started working normally again. Is that normal or should I take it to the Apple store?
