Put 50 cents on a Starbucks card, never use the card, then each day you go into a Starbucks, enter in the card #, get 2 hours free access per day? How could that possibly work?

From Business Wire
"In recognition of the many T-Mobile customers who enjoy visiting Starbucks, the Company is also announcing that T-Mobile HotSpot customers will be able to continue to access Wi-Fi services at no additional cost, through an agreement between AT&T and T-Mobile."

Length of agreement between AT&T and T-Mo?
So, can I now roam at AT&T hotspots using my T-Mobile account or only roam at AT&T hotspots at Starbucks?

The latter would make my T-Mo hotspot service (discounted b/c I'm a T-Mo wireless customer) much more valuable. .... Lemme get this straight, I still get everything T-Mo gave me, plus AT&T roaming? No way that could work.
