Check out this awesome warning, apparently real, that happens when your iPhone’s internal temperature gets above safe operating levels. I love that it refers to itself in the third person. “iPhone is hot. Go get iPhone a beer. Then you can use iPhone.”
It’s a little disturbing that you could be carrying something in your pocket, next to your associates, that is approaching surface-of-sun levels of heat inside. I’ve found my G1 warms up pretty nicely, but the iPhone has even more junk packed into it and no built-in vent provided by the split design of the G1. I advise blowing softly into your iPhone’s charge port.

Based on the signal strength indicator, it appears that the phone pictured above is somewhere in Manhattan.

I know when I used the Flashlight app the phone heated up pretty quick.
Looks like a good app.. but as you say with that notification.. beware of where you are and whose around lol!
