Joel Dickinson - Code Break
This is a strong piece of magic to be performed with your iPhone.

With no gimmicks, mathematics, written predictions, apps or dual reality a participant is able to examine, lock and then amazingly unlock your iPhone by correctly guessing your PIN code.

This is a tried and tested routine which gets big reactions every time.
