In advance of getting my iphone I set up itunes with my music, apps and movies. I just attached the iphone to the computer and sync'd it, and it added the apps, but none of the music or movies were added to the phone. What am I doing wrong? On the left side of the screen, it has my iphone listed under 'devices' but none of the music etc has been added. Can someone help? Is my first iphone (had an ipod before but is set up on a different computer to this one) Thanks.
