I just got the new Iphone 4 and my Dad has 2 mac computers his mac (big box computer) is running OS X its has farely old but it is the itunes he has his iphone 3gs synced to and all the apps, music/movies most of which I have bought and he doesnt want to upgrade to leopard bc he says it makes is mac run slow bc it wont be able to handle it. Since he wont upgrade his software when I tried to sync my iphone 4 it said I need OS X 10.5.8 or later. So I had to sync it to his macbook pro running snow leopard and now I have no music and no apps and no movies
Is their any way I could sync the two computers and drag the things I want over. & I wouldnt be copying them or trying to steal them just take them off one computer and putting them on another. If anyone knows any way possible I could do this it would be extremely helpful. Thanks.
His macbook pro is new so he doesn't have ANYTHING on there.
