hey, I recently attached my ipod touch to my friends computer. I noticed after I got online with my touch it still showed his username and I needed his password to get apps from the app store. Is it possible to change this back to my itunes store username and password without loggin into itunes store without a pc?? I tried to log onto the Itunes Store App from the touch, but it's not available in this country it says (Kuwait). If I can get logged into that can I change it from there?? Thank you.
