Today, for no reason, after i put my phone in my pocket and took it out a few minutes later, it would not turn on no matter what. I tried everything for like 10 minutes, and then i hooked it up to my computer, and itunes/computer did not even recognize anything. After that, i took it off, and i held the home and power buttons together for a few secs, and it restarted, just like it does when you power it down and start it back up. any ideas what the hell this was? it was a few minutes after i downloaded the hot weather app. so lame. i think i'll call apple and tell them, but otherwise everything seems fine.
