The Nokia Lumia 810 product page is now displayed on the T-Mobile US website. The device, an exclusive variation of the Lumia 820 available on AT&T, is on its way to the carrier but no pricing is yet available. The listing states the Lumia 810 is "coming soon" but we're yet to see any information on availability or how much it'll cost consumers.
We had a quick look at the Lumia 810, which sports a 4.3” OLED WVGA Clear Black display at 800x480 with an 8MP rear as well as a 1.2-megapixel Skype HD certified front-facing camera. In addition, T-Mobile will offer to interchangeable back overs in black or cyan. Hopefulyl we'll have more information soon.
