My partner and I have one iMac, with one log-on (user account). At the moment our iTunes account is in my partners name, however when I get my iPhone I will be setting up my own account. Does this mean that apps my partner has downloaded (for the iPod), will not be available to me for the iPhone and vice versa? Similarly with music, if one of us buys music, will the other one be able to sync it to their device? Thanks.
