Here's Apple's page on how it works with PC's. I think this would be your best bet - once you're set up, you can update your contacts or calendar on your iPhone, PC, or through the .Me web apps and everything will get in sync automatically. It's a great set-up I'm sure you'll enjoy!

i understand what it is and how it works... i was just wondering if the discounted memberships from amazon that you mentioned were able to be used by anyone, or if it used some kind of "mac only" registration scheme.
