If you found your ipod touch is 'dead', ie won't turn on, holding the power button (top right on
Ipod) does nothing, your comp doesn't even recognise it, iTunes also - then you might need to do the following :
1) Start your iTunes and connect your iPod touch to your comp.
2) Keep holding the POWER button (top right) together with the HOME button (centre, bellow the ipod screen) for about 10 seconds. You should hear a sound(s)..
Release the POWER button ONLY,
keep holding the HOME button, you will again hear some sounds.
3) If you did it correctly iTunes will tell you that it has detected an iPhone or iPod touch in recovery mode.
You should be able to re-sync all your previous ipod content from there...
Sorry, if this was already posted somewhere here, but I just recovered my ipod after searching the net, so wanted to share it..
I did donload and re-isntall the latest Itunes before I did the above, so try that if the above doesn't work the 1st time out..
