My friend was charging his iPhone in his car on a hot day. Don't know why he did it, but when he went to get it, it said "Overheated" on it. Has anyone else every experienced this? He let it cool down and than it seemed to work fine. Will this void any extended warranties he has, like the one through Verizon that he pays monthly to? But, now it won't update the weather app and the date is stuck. Could this all be from the overheating? And, Yes, it is my friend, because I'm on AT&T.
