AT&T's Free Wi-Fi Hotspot Access for iPhones Finally Announced? [No]
AT&T knows Wi-Fi is hot, and free Wi-Fi even hotter, which is why we are proud to offer iPhone customers free access to the nation's largest Wi-Fi hotspot network with more than 17,000 hotspots, including Starbucks*. Now users can relax and access music, e-mail and web browsing services with their favorite blend in hand from the comfort of their favorite location.AT&T provides an online tool to find a Wi-Fi spot near you.
We had first reported on this topic back in April when AT&T had turned the feature on at hotspot locations across the U.S. This was quickly disabled just a few days later. Another week after that, AT&T advertised the new feature on their iPhone website, and again quickly removed it. When the service was active, AT&T simply required you to enter your current iPhone phone number as authentication.
There was some speculation that the delay was due to the fact that they had not yet completed their Wi-Fi deployment at Starbucks. AT&T had won the Starbucks contract from T-Mobile in February and is already offering free Wi-Fi access for their DSL and business customers.
Update: AT&T says they made a mistake by posting that page and have made no announcements.
