I apologize since I suspect this question has probably been asked a million times before, and I think I know the answer, but if you'll indulge me. I rarely sync. If I backup my iPhone 4, and then restore that backup to my new iPhone 5, what happens the first time I try to sync to new computer? Since the direction is from computer to phone, won't iTunes try to erase all on the phone? I suppose I could check the boxes not to sync certain thing like apps or songs, but what would happen on future syncs? Am I missing or not understanding something here? What's the point of a sync versus simply creating backups and never syncing?
