I made an iPhone app called "HammerTime!"
Round #1 instructs you to place your phone on a hard surface, find a hammer of any kind, and hit your phone as hard as you can.
Rounds #2 and up instructs you to repeat Round #1.
A permanent blank screen indicates you have won and you may receive a prize (a brand new iPhone!!) if you can convince Apple your phone is malfunctioning because of something they did.
