said by Matt3: Having a *Vision* vs. putting it into order are two completely separate things. They need to have the capital and barely have enough to do network vision. They are way behind even T-Mobile in terms of having a 4G network and they haven't even migrated the network they acquired in 05". said by Jim_in_VA:
yes it does, however GSM and CDMA are not compatible
With the Sprint Vision network retrofit, adding GSM support is a simple matter of plugging a blade into the base station.
Although why support a dying technology? Just migrate the TMo customers from GSM to LTE like AT&T did when they migrated Orange to Blue after the Cingular merger.
