Tomorrow I'm switching over from an iPhone 3g (I know, I know...) to the IP5. Trouble is, don't believe I can transfer all my contacts (can't do it w/ iTunes, b/c my macOS is too old to get the newer iTunes version, and my current/old iTunes won't connect to my iPhone unless I update the version, which I can't b/c of my OS). Vicious cycle. If I bring it into an AT&T store, would they be able to transfer my contacts? Or is there another way I can do it at home?
