I was sitting in class and all of a sudden my iPod Touch starts to heat up, so hot I almost burnt my hand. The previous class it had a full battery, I had shown someone a picture, I locked it back. Then the next class it heated up so fast in not even 20 seconds. I pulled it out of my pocket and it was so hot i dropped it maybe two inches to the desk and the screen cracked from right at the home button to the top left corner diagonally. I tried to turn it on, it wouldn't. I pushed the home button and it heated up even more! After about 40 some minutes it started to cool off. Any ideas why it did that? It's a 32GB iPod Touch (3rd Gen.) with 14GB used, 1 year and 2 months old.
