T-Mobile has announced that it will be the exclusive United States carrier of the Nokia Lumia 810 smartphone. The Lumia 810 runs Windows Phone 8 and sports a 4.3-inch OLED WVGA Clear Black screen, 8 megapixel Carl Zeiss rear camera and 1.2 megapixel front camera (Skype HD-certified!) It sounds awfully close to the Lumia 820, although from the image we were given, doesn't look anywhere near as slick. As lame as it sounds, T-Mobile has not announced pricing or availability, other than to say that the Lumia 810 will be available "in the coming weeks."
