I personally haven't heard anything but it might be something regarding their non contract plans. I know we don't cover them anymore (although we still offer the old plan), plus I believe as a company we have been moving further away from t-mo. In our store we don't even offer it unless you mail the phone. Seems stupid but hey, they pay the bills!
Aloha, Im Matt and I love life.
