I had a different email account when I downloaded iTunes to my computer, and had NO problems syncing my iTouch to that same iTunes account, but when I tried to sync my iPad (which had a different email) to that same iTunes acct. Im not able to sync it no matter what I try i cant sync either my music playlist OR my APPS from my iTouch to my iCloud. When I tried to ADD new email to my APPLE ID preferences, it comes up with a message saying "That Apple ID is already in use".....but I had signed out of my PC email? Please someone help, I would be so grateful as I have been trying to figure this out on my own for almost 2 months. My husband suggested this since calling 1(800)MY APPLE won't help unless I pay $20.00 for Each question!
