What do you do your iPod touch shuts down by itself and the problem isn't the battery?

Plug in your iPod to a computer and open iTunes and then:

-You have to press the home button and the power button at the same time for about 20 seconds. Then release the home button but keep on pressing the power button for a further 8 seconds or so.

-After that on the screen of your computer it will say that an ipod is on recovery mode and you press ok.

-Your ipod will restore and after that it will update.

All you have to do is sync in all your apps and your music form the computer to the ipod touch and the work is done.

(this will not stop your ipod from breaking down but it tells you what to do in case it breaks down again).

And dats all hope u good luck mate :)
