Glenn Fleishman writes "T-Mobile sent me the text of a lawsuit they filed yesterday against Starbucks. The telecom firm alleges that Starbucks didn't involve it in any discussions to launch their free loyalty program Wi-Fi service this week with AT&T. AT&T is gradually taking over hot-spot operation from T-Mobile, market by market over the course of 2008. T-Mobile told me Starbucks is essentially giving away something that isn't theirs. T-Mobile has sued to halt the two-hours-a-day of free service, and is asking for money to cover losses. This might sound like sour grapes, but T-Mobile still operates most of the network, and says that the terms to which they agreed with Starbucks and AT&T for the transition and with AT&T for bilateral roaming don't cover this situation at all. Maybe free access in exchange for buying a cup of joe every 30 days was too good to be true (this soon)."
