I could find the T-Mobile Hotspot login in the AT&T hotspot splash page in Starbucks the last time I dropped by one with my netbook. However, I noticed that the Seattle’s Best Coffee (owned by Starbucks) shop area in the local Borders Book Store had an actual T-Mobile Hotspot instead of the grandfathered (for another 3+ years) access via AT&T Wireless in actual Starbucks shops. Looking at T-Mobile’s list of hotspots, I see that the wireless service is actually provided by Borders itself and that the Seattle’s Best Coffee shop area benefits from that.
