For the first time my iPhone locked up at a blank screen. By blank I mean as if the phone was turned off. I picked it up to use it and nada. Upon closer inspection, there was a very faint "thinking" icon (lines arranged in a circle that "spins" while the phone is laughing at you). I had to reset it to bring it back to life. I wouldn't have thought twice about it, but later the same day it happened to the wifey. We both have iPhone4S's but didn't have the same apps running. So this might be a cool story bro, but I'm curious if it happened to anyone else.
