That happens when you use the app store 

In Owner alleges iPhone 3G became red hot

I've had that happen (well, not catching fire but getting quite hot) when the phone has a problem, usually when it gets stuck installing an app, then you go to the app store which then hangs and the back can get quite hot (more or less where the mark is in that picture). Shortly after that it will reboot.
