I was just viewing photos on my 64GB WiFi iPad when it suddenly froze! It didn't accept touch input, I couldn't press the home button, and sleep/wake and force quits didn't work. Now its switched to an Apple logo with a little "please wait" spinner in front of it, and doesn't seem to be frozen, but still won't respond to my input. EDIT: Nevermind, the problem fixed itself. My iPad just rebooted after about five minutes, although it is scarily hot now. EDIT2: I was surfing photos again, and when I came to the same photo it happened on last time, it happened again! Could there be some kind of virus in the photo or something?!
