Right. I have a iphone 4, my brother has a iMac which for years I've syncd my iPhones with. I bought a 13" mac book last week. I never hooked my iPhone up to my macbook before. Now the problem I'm faced with. I bought a 4s on launch day, I want to start syncing and backing up my 4s to my mac book not my bros iMac. I have loads of photos on my 4 and all my contacts are on that too, I can't loose these! especially the photos! How do I get my info off my 4 onto the iPhone 4s but then use my macbook instead of using my bros iMac?
