Non-Standard Cell Phone Uses

I know cell phones are primarily for talking to people that are somewhere else, but golly gee whillickers, they have some fancy other uses. I'm sure others of you have used them for clocks (who wears a watch anymore?) and for alarms (who travels with an alarm clock or wants to depend on the one in the hotel room?).

But do you use yours as a flashlight? I do. Every morning I get up, get dressed in the dark, so as not to disturb the sleeping husband, grab my phone off the nightstand, and step into the dark house that exists outside of the bedroom at five o'clock in the morning. It's a scary place, and I don't keep it as picked up as I should. To avoid stubbing my toe and making all manner of loud noises that would undo all the quiet dressing I did moments before, I open my phone and let the soft blue backlight lead the way to my upstairs office.

Any odd uses you put your phone to?
