Good news, Magenta family! T-Mobile has announced that its Extended Range LTE (aka 700MHz, aka band 12) is now live in another major market, and I’ve got lots more sightings to report today, too.

First up, T-Mo says that Extended Range LTE is now live in the greater Atlanta, Ga., area. This includes Atlanta and its surrounding Perimeter as well as Marietta, Roswell, Alpharetta, Gainesville, Dalton, Rome, Newnan, Carrollton, Covington, Conyers, Athens/University of Georgia, La Grange, Ringgold, and “many other smaller towns throughout northern GA and in part of AL along the GA border,” including Lafayette and Huguley.

Meanwhile, many of you have pinged me in the past week with more band 12 sightings throughout the US. Here’s where you’ve found it:

Orlando, Fla.

Evansville, Ind.

Steamboat Springs, Colo.

Dallas, Texas

Queens, NY
