I want this to go into the iPhone 5. If it does, I can think of about a million ways to troll the general public with it.

Imagine, little solar-powered IR LEDs that you could ninja-drop in places (like...an Apple store) that would broadcast "Hello, you are photographing a copy of The Hurt Locker". This would make the best hidden-camera show ever (though you'd have to record it with a non-iPhone).
