transition to AT&T-provided WiFi sometime this spring, and it looks like T-Mobile's getting the boot right on schedule. The first Starbucks to switch over is just 4.2 miles away from AT&T corporate headquarters in San Antonio, at 5321 South Broadway Road, and the rest of the country should come on market-by-market. Anyone else seen any activity? T-Mobile customers still getting access, as promised? Let us know in comments!
