With all the talk of the Cloud and all, I was wondering if there are any major differences in the way sync works with iOS 5 versus 4. Is usage of the "cloud" optional? Will I still be able to add and remove what playlists and such get synced to the phone with iTunes? What about apps and photos and such? I don't really trust the cloud too much, so I still want to have a full backup of everything on the phone on the computer. Call me old-school; that's how I feel.
