The Nokia Lumia 900 could be launching March 2012 according to a Nokia developer newsletter which was posted recently, it also suggests the phone will be available on AT&T.

The news comes after the Lumia 900's official unveiling at CES 2012, with the post stating that: "it will become available exclusively through AT&T in March".

There is, however, no word on any UK launch date. If the phone did arrive on UK shores it would join the Nokia Lumia 800 and Lumia 710, the 710 coming to the UK 1 February, as the third handset in Nokia's smartphone fightback; each features Microsoft's Windows Phone OS. The Lumia 900 has been pitched as US-only so far.

The Lumia 900 is quite similar in looks and functionality to its smaller brother, the lumia 800, which has been very well received, but it gets a few boosts with a bigger 4.3-inch AMOLED screen and a 1.3-megapixel front-facing camera.

Are these three Lumia handsets going to turn around Nokia's fortunes? Let us know your thoughts in the comments below.
