Hey guys, Today at work I had my phone in my pocket. I heard my phone ring once and then stop. I figured it was a call that was accidentally dialed, or something along those lines. So, after a few minutes I pulled out my phone to see who called me, when my screen had the "Temperature screen". Why would this have occurred? I'll probably go to my local Apple store within a few days to get my phone checked out, but I'm thinking it's probably not a big issue. I've read other threads about people having that error screen while leaving their phone out in direct sunlight or inside their car. Though, what makes the situation odd to me is my phone was in my pocket, with no heat sources near me besides my body, and the temperature was in a dark 72 F. I even felt the phone in my hand and it was not warm whatsoever. Any ideas? Software fault? Had to restart my phone in order to get it to work again. Thanks. I do own the iPhone 4.
