Earlier this morning, Sprint released a slew of press releases announcing the introduction and expansion of 4G LTE in Massachusetts, Indiana, Texas, Tennessee, Pennsylvania, and Puerto Rico. Here’s the full list of all the new cities and regions that can now experience Sprint’s LTE in all its glory:

  •  Austin, TX
  • Boston, MA
  • Bryan-College Station, TX
  • Columbia, TN
  • Emporia, KS
  • Fort Wayne, IN
  • Framingham, MA
  • Gettysburg, PA
  • Western Puerto Rico, including Aguadilla, Isabela, Cabo Rojo, Mayagüez

Additionally, Sprint says that better 3G coverage and data speeds are also available in these areas, which is most definitely welcome news to anyone who has experienced Sprint’s lackluster service as of late.

Even with this latest announcement, concerns are still rising among Sprint subscribers that Sprint’s Network Vision initiative is falling too far behind schedule. Many parts of the nation that were promised WiMAX and never received it are now waiting for LTE coverage, and reports abound of people who experience speeds slower than dial-up internet in 3G coverage areas. Sprint hasn’t officially announced any changes to its original timeline of being largely complete with its LTE rollout by the end of 2013, but unless Sprint can figure out a way to catch up, more delays seem inevitable.
