Is this a new feature of 2.0? Every time I sync my iPhone it does a "backing up" - which takes a while. It used to be if there was one song to add, it did it in a couple of seconds - now it seems to do a "back up" which takes about 10 minutes. It is very annoying. Is it anything to do with the fact that I have mobileme (which is not working yet) on the phone?
