I accidentally left my iPhone 4 in my car late this afternoon while I was in an appointment. I had the windows cracked open, but it was probably 90 something outside. When I got back in the car about 30 minutes later, I saw my phone sitting in the cup holder and thought oh #$%&! I pressed the home button and this is what I saw. Unlocking the phone would only put it in emergency call mode. I hurried up and started the car and got the AC cranking and then started driving home while holding the iPhone against the air vents. It took about 15 minutes to cool it down to where it woke up to the normal unlock screen. Whew! I was pretty worried that I had fried my phone. Just a lesson to not leave children, pets or iPhones in your car on a hot day!
