applicationWillResignActive
When you turn off your iPhone while an app is running, that app gets sent an “applicationWillResignActive” message to tell it to stop running things like recurring timers or whatnot. I just recently noticed that a certain exploding dice game does not properly do this when I continued to hear a tick-tick-ticking even after I turned off the phone. So … umm, yeah, make sure your apps don’t do that.

Now, some apps will want to not resign active. Pandora, iPod, GPS navigation. Stuff like that you know.
