Cool Trick With iPods!

Step 2 Bring It Into Diagnostics Mode

While the little "apple" symbol is displayed on the screen press the center button and the back button at the same time.

It may take a while to load into diagnostics so don't take you fingers off of the buttons for about ten seconds, If it brings up the main menu before then you can stop (it didn't work).

You'll know that it worked if you see something akin to the picture below.

It took me about 6 times to get it right so don't feel frustrated, the touch wheel buttons are really sensitive and the commands don't always work...
