No. Only if you delete the programming and then reload it.
Connect your iTouch to your computer and click "Restore iPod" and it will erase everything on your iTouch.
If you can connect to the internet with the Itouch, then I believe you can.
an itouch is a phone as a ipod is just a music player
Updating the iPod Touch software erases the jailbreak. You can update, but it will erase your jailbreak.
you go to my computer and click on it and then save it and then loook at your itouch and then you will have it
You need download iTunes to your pc,and connect your itouch to your pc. Now open the iTunes, don't need to sign in the account, if you have,it is better. Find you itouch album from iTunes, and drag your music from pc to itouch ablum in iTunes.
that leave your ipod like when it was new, reset to factory condition
Yes. But if it is tethered, you will have to use the program you jailbroke it with to reboot it. This will not erase anything on your iTouch.
