Some Macrumors readers are reporting that AT&T’s Starbucks and Barnes and Noble Wi-Fi hotspots are coughing up free internet access for iPhone users. When you hit up the wireless at these locations, you get directed to a special iPhone-formatted page that asks for your phone number. Once you punch that in, you’re free to check email and Facebook at decent speeds. AT&T declined to comment, but didn’t officially deny anything. [MacRumors]
