AT&T Withdraws FCC T-Mobile Application, Will Focus on DOJ
DING DONG the witch is dead!
If DT still wants to sell out, I think Google would be ideal. There's already an established relationship (T-Mobile has been the Android testing ground) and T-Mobile would get an instant boost from the name recognition.
All in all, T-Mobile will do just fine if they just improve handset selection and work on some better roaming contracts.
