A "Starbucks purchase card" is like a gift card. Except they encourage people to buy one for themselves, so that you don't have to carry cash. I guess if you use a gift card to make a purchase, then they can tie your purchase to an AT&T account, and they'll give you 2 free hours of WiFi service. No one's said that they'll be offering any extra free services for iPhone users, which makes me assume they won't. (AT&T already runs WiFi hotspots now, and those aren't free for iPhone owners.)
