The Nokia Lumia 900 is expected to be unveiled at CES (Consumer Electronics Show) 2012 , which officialy gets underway tommorow in Las Vegas.

The Lumia 900 will be the highest mobile in Nokia's Windows smartphone range and will eclipse the Lumia 800. However, in many ways the smartphone will be very similar to the Lumia 800.

The main difference is that the Lumia 900 will have a larger 4.3 inch touch-screen, which is 0.6 inches larger than Lumia 800's screen. The rest of the specification is expected to the same meaning it'll have a 1.4 GHz processor, 16GB of on-board memory and 512MB of RAM.

It'll also have an 8 mega-pixel camera, but rumours suggest that it could be a slightly tweaked version. You'll be able to connect via 3G or WiFi, so you'll never be without internet access and it'll run on Windows Phone Mango (7.5).

Once the Nokia Lumia 900 is announced at CES we'll bring you all the details about Nokia's new Windows phone.
