So i went to sleep last night after the battery was fully charged on my 4th gen Ipod Touch. I unpugged it and set it next to my phone. I woke up in the morning because it was SOOOO hot. It started cooling down and the screen cracked. It hasn't worked since and I will probably drive to an Apple store(two hours away) tomorrow. I just want to make sure this won't be a wasted trip. Gas is expensive! Thanks for your help.
