Don't you hate it when your friends with crappy Android phones loaded with crappy games asks to borrow your iPhone to play something that isn't crappy? Then they bleed the battery dry and you feel like a used tool. Crappy!
Play Dead is an app that fakes like your iPhone is dead with a loop of the shutdown screen. That way the next time your crappy friend asks to borrow your iPhone, you just fire up the app, flash the screen and say sorry dude, phone's dead. Free. [iTunes]
