Check out this hacking video tutorial to learn how to hack a cell phone with a magnet. You can easily hack Verizon's Motorola RAZR mobile phone to bypass the user password.
Turn off the MOTORAZR phone and then turn it back on. After the red Verizon introduction screen comes on, it will ask you for your password if you have it enabled to do so.
Turn off the cell phone again, then turn it on again. While the red screen pops up, hold the magnet over the "END" button, and it will automatically bypass the security code.
