We'll likely see additional Nokia Windows Phone announcements at CES 2012, but for now, Nokia is making waves in the US market with the Nokia Lumia 710.  Coming to T-Mobile on January 11 for $49.99, the Lumia 710 offers a 1.4 GHz Snapdragon CPU, 3.7-inch WVGA display with Nokia's ClearBlack technology, a 5-megapixel camera with 720p HD video recording, and Windows Phone 7.5 (Mango).  It's one of T-Mobile's best mid-range devices, and should be perfect for those moving to a smartphone for the first time.  Part 1 of 2.
