i'm a new user. when i connect my ipod touch to my macbook pro, it connects and then a little while later will disconnect. then it will connect again. it does this constantly. it is especially frustrating when i am in the middle of a sync and it suddenly disconnects. i have had to restore my ipod oftentimes because the sync didn't go through and then itunes is unable to read the ipod touch correctly. anybody know of this issue and can help? thanks in advance.
