Note: This only works on iPads and iPad minis.
This doesn't work in iOS 7.1 DO NOT UPDATE!
Step 1: Choose Any App
To start this prank, you need to open any app. I chose to use the clock app but any app works.
Step 2: Cause a Glitch
After opening the app, pinch to the home screen with four or five fingers but don't let go. With one finger quickly swipe in one direction. You will need to have more than one page for this glitch to happen. Don't worry if it doesn't work at first, it isn't easy.
Step 3: Finish the Prank!
Now you can turn off the device. When you go to the lock screen it will only show a screenshot of the app when you were last in it. There will be no way to unlock the device, open any apps, open notification center or command center, and even Siri can't open any apps!
Step 4: How to Undo the Prank
It may seem irreversible there is a way to fix it. The only way to undo this prank is to restart the device by holding the home button and the lock button until the device restarts.
