How long will this last? It seems that there are reports of free WiFi for those with a iPhone in their left hand, and a double tall latte in the right. As you can see from the pic, at&t has a "number" input screen that will allow you to connect to a Starbucks or Barnes and Noble hotspot for free.
I doubt that it will be free for too much longer, and if so, Starbucks is going to look awefully weird in the next coming weeks. There will be tons of iPhone users glued to their screens and wired at the same time.
A bad combination.
