T-Mobile confirms network update will disconnect these devices

It seems that carriers share a common theme this year of "out with the old and in with the new". In most cases, that refers to their desire to finally shut down 3G services, a move that has been met with resistance that forced some network operators to delay their plans. T-Mobile, however, has one network update coming that is both mysterious and also inescapable. By the end of the month, as many as 19 devices, will no longer be able to connect to its network, forcing users to upgrade their devices, presuming they haven't yet.
