I just bought a mbp 13. I plug in my iPhone and I want to transfer. I don't sync since I was told that it would erase my iPhone of all my music and apps. I want to transfer but I keep getting asked for my apple id and it gives me a different id. I change the id and then I enter my password and I get a message about my apps not authorized and I will lose my apps. So I type in my id and password and then I get caught up in a loop and it starts all over again asking me for my password and id. I don't have iOS 5 yet for my iPhone. Why can't I transfer my stuff over to my new mac. Before I had a windows pc and it crashed so I can't transfer via the pc. This is ironic since I was told it was seamless to transfer my stuff (music, photos, apps to the mac book pro. Help.
