A couple of MacRumours readers have reported that AT&T hotspots are now offering free Wi-Fi access to iPhone users. Barnes and Noble, Starbucks and presumably AT&T’s 71,000 other Wi-fi hotspot locations are now offering iPhone users a custom portal to access free Wi-Fi. A special iPhone formatted page asks for your mobile phone number. Once entered, you can access the Wi-Fi access for free.
MacRumors has been able to confirm this finding at a local Barnes and Noble.
