Ipod reboot

My ipod locked up this morning - it would not respond to any buttons but it would detect the lock being slid across as the lock icon would appear or disappear on the screen. I got to work, mentioned it to my colleague who promptly started to google it. Much to our amusement the first result after typing in reboot and then a space was reboot ipod.

After pressing the menu and center buttons twice, the ipod unfroze and I was able to listen to my podcasts in the car this morning.
