iBroke is a fun toy that lets you play a joke on someone who wants to use your iPhone or iPod Touch.
iBroke is a simple toy to scare your friend into thinking he broke your famed device. Load up the app and select what problem you want to occur. Then you’ll be presented a simulated lock screen which your target is then given. He’ll unlock and try to launch an app, to his surprise, he some how broke your device.
Feel free to freak out.
