T-Mobile announced that it will exclusively offer the Nokia Lumia 810 in the near future. The Windows Phone 8 smartphone is closely related to the Nokia Lumia 820, save for a slightly different looks and the presence of T-Mobile's 42Mbps HSDPA.

The Nokia Lumia 810 will feature a 4.3" WVGA Clear Black display and 8MP main camera. A 1.2MP front-facing unit is on board as well. Interchangeable back covers and wireless charging will be available too. Nokia and T-Mobile have not revealed any further hardware specifics.
Software-wise, the Nokia Lumia 810 will boot Windows Phone 8. The usual set of Finnish tricks such as Nokia City Lens, Nokia Music, Nokia Drive, and Nokia Transit will be at your service as well.
Pricing and availability of the Nokia Lumia 810 are yet to be revealed. We doubt it will be a long wait though.
