Nokia will unveil its first Windows phones - Lumia 800 and 710 - known previously as Sea Ray and Sabre respectively, at Nokia World on Wednesday, according to Winrumors.

The site also released a series of photos of  Lumia 800 and 710 saying Nokia CEO Stephen Elop will introduce at least two Nokia Windows Phones. The site expected that both devices will be made available in select European markets in November with U.S. launches in 2012.

According to the rumors, the Lumia 800 is similar to Nokia N9 in design, a MeeGo-loaded smartphone with a 3.9-inch AMOLED screen, while the Lumia 710 may feature 1.4GHz processor with 1GB RAM, a 5-megapixel camera, and 3.5-inch, 480x800-pixel touch screen.

It is not surprising. Windows Phone division President Andy Lees had given a clue during  Asia D conference on Oct. 19.

Next week it's going to be Nokia World, where they're going to announce their phones and how they're going to make the most out of the Windows Phone opportunity, Lees had said. 

In addition, Nokia and Microsoft have already expressed that they would cooperate with operators to support the platform.

Operators really want to have another company on the scene: they don't want Google and Apple to rule the mobile universe, Chief Executive of Barcelona-based mobile app development firm Golden Gekko Magnus Jern said.

Nokia World will kick off on Wednesday with a keynote address by Nokia CEO Stephen Elop at 1 a.m. PT.
