New Apple iPod Nano - new Lockup - new Reset technique
Yesterday, my wife gave me an early Christmas present of an Apple iPod Nano 4GB. (woohoo!)
Five-minutes after opening the box, I received my first (and hopefully last) lockup. For reference, here is how you reset an iPod Nano:
- Toggle the "Hold" switch On, then Off again.
 - Press and hold down the Menu and Center buttons for several seconds.
 - The unit should reset to factory defaults.
 
Note: you will have to reconfigure some lost settings after this.
