I've noticed recently I get this Temperature screen when I leave my phone in the car at the water park. I don't want to take it in with me since I'll probably get it stolen or wet. But whether I leave it in the trunk or in the glove box it still comes up with this Temperature issue. Do you think this is bad? What precautions should I take? I'm weary of leaving it in the cooler since it might end up getting wet, and I'll never get a Apple Store swap for replacement. Any help?
