When T-Mobile announced earlier this year that it would be upgrading its 2G network to 4G, it’s fair to say our attention was grabbed. T-Mobile’s reputation of having great, fast coverage in major cities and having poor coverage elsewhere has been a big hindrance to many people joining the carrier. But times – as the famous song goes – are a-changing.

Over the past couple of weeks we’ve been informed by a good number of T-Mobile fans that they’re starting to see 4G, both HSPA and LTE in areas where they previously only got 2G/EDGE. In some cases, the network is still in the very early stages of being upgraded, and so speeds don’t climb that high. But, 4G is still showing up on people’s phones, in the status bar.

One reader got in touch from New Mexico, sadly with not screenshots or speed test. But the experience is encouraging nonetheless:

“Hi! I live in Albuquerque, New Mexico, and make the 250 mile drive down south to Las Cruces, New Mexico about once a month. For the last 6 years I would be stuck on 2G all the way down I-25, (the only road there, check it out) but now I am starting to see HSPA+ for at least 100 miles! Sensorly.com is showing it around Socorro right now, which is pretty awesome.

At the same time, I drive north on the 550 to Farmington, New Mexico once a month, and exactly the same thing is happening on that road!”

We also had another with news that 4G has been showing up in central-south Utah along the I-15 corridor. But that’s not all. The following locations are also seeing an upgrade:

And these aren’t the only locations. This is but a handful of places we’ve been told about. There’s a growing forum entry on Howard Forums with other T-Mobile users updating when they notice a T-Mobile 2G upgrade to 4G taking place. All-in-all, it’s very encouraging.
