T-Mobile has launched HSPA+ service in the company's 1900 MHz spectrum in several new markets, and the carrier continues to woo unlocked device owners. According to a blog post by T-Mobile Chief Technology Officer Neville Ray, the company has turned on 1900 MHz in Seattle, Minneapolis, Atlanta, and additional portions of the Bay Area. The full breakdown of the expansion, according to Ray:

•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.

The carrier announced last week that they'd not only start selling the iPhone in 2012, but they'd be getting rid of the carrier device subsidy model, with customers paying either the full price for devices, or paying their device off in monthly installments. While the iPhone launch is good news for some, T-Mobile's network is far from prepared for the device, so you can expect the iPhone to drop sometime in the second half of 2013 alongside the company's first LTE deployments.
