Just do a search for "flashlight" on iTunes.
$4.99 white screens, and 100s of them
Now search for "flashlight" on the Android Market.
About 50 crappy bright screens, but they're free, and the awesome camera flash for free as well! Just sayin,
My friend dropped his pen on the bus and used a $0.99 white screen to look for it. I turned on the free MotoTorch and it lit up the entire back of the bus.
