Sprint also expanded their network to cover Wichita Falls, Texas, which is a couple hours outside of Dallas. 4G LTE was also turned on in Hutchinson and McPherson, Kansas, two towns in the center of the state and several hours from Kansas City.
Finally, New Bedford and Fall River, Massachusetts, neighboring towns which lie well south of Boston, also had the switch flipped to provide high-speed service. Sprint has set an aggressive goal to have over 100 cities up and running with their new LTE service in the coming months. While no definitive time-line was given, at the rate the carrier is moving, they will likely reach that goal in the early part of 2013.
