According to this Associated Press story, customers will be able to use their Starbucks card to buy something and get two hours of free Wi-Fi. Those looking to surf longer can also pay $3.99 for another two hours or buy a monthly membership for $19.99, which includes access to any other AT&T hot spot. By comparison, T-Mobile charges $6 per hour-long session to $9.99 for a day pass to $39.99 a month for unlimited access.
Current AT&T DSL customers will reportedly get unlimited free access, as do all Starbucks employees. Interestingly, T-Mobile hotspot customers will also get free access thanks to an agreement set up between T-Mobile and AT&T.
