The Nokia Lumia 710 for T-mobile is now official after several leaks. Nokia’s first Windows Phone device in the US is remaining mostly stock with the addition of T-Mobile TV, T-Mobile My Account, and Telenav GPS. It’s expected in stores January 11th for $49.99 with 2 year contract.

Available in a black or white finish, the Nokia Lumia 710 features a 3.7-inch ClearBlack WVGA scratch-resistant display, 1.4 GHz Snapdragon processor, a 5-megapixel camera, and more. Take a look at this hands-on video we shot of the International version during Nokia World 2011.

My mom is currently a T-mobile subscriber whose 2-year contract is ending in February. She currently has a Nokia dumbphone. It’s time for her to get a smartphone and I know exactly which device to recommend: the Nokia Lumia 710.
