Help! my iphone is severely frozen! it is super hot and will not respond to anything. it has been kind of weird for a couple of days...the battery has been dieing really fast. but i tried every suggested in the troubleshooting and nothing works. it will not turn off, it will not restart, it won't even respond (and neither will itunes) when i plug it into my computer so i cant even restore it that way. what should i do?
