T-Mobile continues to push forward with its network refarm, today announcing that it has strengthened its mobile network in three key markets. Those living in Seattle, Minneapolis, and Atlanta should see faster data speeds on unlocked devices. T-Mobile’s network refarm seems to be coming along swimmingly, as it was just last week that the company announced it had expanded 4G service in a number of other markets.

Of course, while T-Mobile says that it has improved its network in Atlanta, Minneapolis, and Seattle, there are a handful of surrounding areas that are also experiencing improved data speeds too. T-Mobile has also been continuing to expand on the enhancements made in the San Francisco, Oakland, and Silicon Valley last month. Here’s the full list of areas straight from T-Mobile:

• Atlanta, including the surrounding cities of: Roswell, Alpharetta, Marietta, Covington and Conyers
• Seattle, including the surrounding areas of: Lynwood, Bothell, Mill Creek, Edmonds, Redmond, Kirkland, Woodinville, Bellevue, Issaquah, Sammamish, Kenmore, Mercer Island, North Bend, SeaTac, Burien, Tukwila, Renton, and Lake Stevens
• Minneapolis, including the nearby cities of: St. Paul and St. Cloud
• Additional Bay Area cites include: Fairfield, Monterey, Napa, Petaluma, Salinas, Santa Cruz, Santa Rosa and Vallejo.

In other T-Mobile network news, the company said that it’s continuing to modernize its network in areas like Boston, Chicago, San Diego, New York, and Los Angeles, so be on the lookout for faster speeds if you live in one of those areas. This network refarm is part of a plan that sees T-Mobile putting up a whopping $4 million dollars, so the company’s network modernization can’t exactly be called cheap.

This is all happening while we wait for T-Mobile to launch its 4G LTE network. It has said plenty of times in the past that it will begin rolling out 4G LTE in early 2013, so there may not be much longer to wait until T-Mobile enters the 4G LTE space.
