im not sure why you would do that
but download the 1.1.1 firmware, then go into itunes, hold SHIFT and click 'restore' it then asks you for a file, pick the 1.1.1 firmware, and then let it restore the ipod
is there a way to make my ipod go to 1.1.1 even tho it is a 1.1.4, i tried using the ziphone software on it but it didnt work
best way to go is iTunes 7.5
