I had a MBP which I used to sync all my music & movies to my iPhone. I got a new MBP and moved everything over from the old MBP. On my iPhone, I have playlists that I really don't want to lose. How do I sync my current iPhone's playlists, etc., to the new new MBP. From what I can tell, in Finder if I click sync, it takes what's on the MBP and wants to sync it to my phone. I'm guessing it doesn't take what's on the phone on put that on the computer, right/
