EC-: I know this isn't the usual vein of GOG Q's, but I'm unfamiliar with Apple products so here goes:

My Dad just picked up a used iPhone 4 from a friend of his. He needs it for work, he'll likely only ever use it for e-mail, Google maps and taking notes. Probably no media use. My question is: Should I go help him set up iTunes on his computer? As in, is it necessary given his purposes? I've been told by some people it's necessary just for activation and by others that it is not needed at all. Thanks.
