I've just bought a new macbook pro and want to transfer everything on my iphone 3gs on to this laptop to have itunes on it connected to my iphone. Could somebody please tell me the best way to do this? i'm worried about connecting my iphone to it and accidentally erasing everything off of my iphone. My iphone is synced with my old macbook but I haven't used this laptop for 2 years, hence why I haven't migrated data from it to my new computer. Many thanks!
