Just a week after T-Mobile announced that its 1900MHz HSPA+ coverage was live in Atlanta, Minneapolis and Seattle, the magenta carrier has revealed another five areas that are now lit up with the newly-modernized network. Included in this is Chicago, Reno and a trio of California markets. Here's how the full list breaks down:

• Chicago, including the surrounding areas of: Aurora, Berwyn, Chicago Heights, Cicero, Des Plaines, Downers Grove, Evanston, Evergreen Park, Naperville, Oak Park, Schaumburg, Wilmette and Winnetka.
• Reno, Nev.
• Sacramento, Calif., including the surrounding areas of: Antelope, Citrus Heights, Elk Grove, Fair Oaks, Folsom, Loomis, North Highlands, Rancho Cordova, Rio Linda, Rocklin, Roseville, Vacaville and West Sacramento.
• Fresno, Calif.
• Southern Calif., including: Alhambra, Anaheim, Claremont, Culver City, El Monte, Encino, Garden Grove, Granada Hills, Inglewood, Irvine, La Crescenta, Laguna Niguel, Monrovia, Monterey Park, Newport Beach, North Hills, North Hollywood, Paramount, Pasadena, Redlands, Reseda, Rosemead, Santa Ana, San Fernando, San Gabriel, Santa Monica, South El Monte, Temple City, Torrance, Upland, Valley Village, Van Nuys, Westminster and Wilmington.

T-Mobile's 1900MHz HSPA+ service now covers 23 areas and 100 million people across the country. The network enhancements made by T-Mo in these areas offer improvements to voice, data and in-building coverage, as well as faster data speeds for unlocked AT&T handsets, including the iPhone.

T-Mobile has been fairly steady in rolling out this coverage in recent months, with the expansions picking up in the past month or so, which is exciting to see for all of the Magenta Army members out there. The carrier says that network enhancements are continuing in areas like Boston, Chicago, Los Angeles, the New York metro area, Philadelphia, and San Diego, so keep it locked to PhoneDog and we'll give you a shout once more areas officially go live.
