Nokia’s 800 “Lumia” Windows Phone looks set to be unveiled tomorrow.

The final branding of the device is all but confirmed following a set of photos uploaded to photos sharing sites. The photos were uploading using a “Nokia Lumia 800″ device. The Nokia Blog spotted the photos and confirm that the device features a f/2.2 aperture, similar to the Nokia N9. The Lumia naming has cropped up before on Occasional Gamer lists. Lumia means “art from light” and could match up to Nokia’s first Windows Phone adverts that mention “today the sun will rise and set. The rest is up for grabs.” Teaser commercials for Nokia’s first Windows Phone started to air over the weekend on British national TV and also feature a number of artistic disco lights.

Nokia CEO Stephen Elop is expect to unveil at least two Windows Phone devices on Wednesday. There has been a large number of leaks related to Nokia’s devices and the company appears to be readying a “Searay” device and a “Sabre” device for initial select markets. Elop will detail Nokia’s N800 Lumia Windows Phone on Wednesday morning. The N800 Lumia, know previously as Searay, is expected to be made available in black, blue and pink initially. The 800 includes a 3.7inch AMOLED display, a 1.4GHz processor and 8-megapixel rear camera. Nokia’s second Windows Phone device, known as the Sabre, is also expected to be revealed. The device is likely to be similar to the 800 but will ship with a 5MP camera and 8GB of storage to ensure it’s a low cost offering.
