Nokia has just announced the Nokia Lumia 900 in the US on AT&T, complete with LTE connectivity.

The new device, which comes with a 4.3-inch AMOLED screen, will sadly only initially be available in the US and become the country's flagship Windows Phone 7 leading the charge alongside the HTC Titan II on AT&T.

"We shipped the the world's first real Windows Phones," said Nokia CEO Stephen Elop kicking off the launch of the new phone. 

The new model on the design stakes is virtually identical to the Nokia Lumia 800, coming in a polycarbonate case in black and cyan. The Yanks might not be getting the Lumia 800, but they will be getting a phone that looks the same, only bigger.

That means that the screen and phone's components slip into the same case design, however different to the Lumia 800 is both the positioning of the micro SIM slot and the Micro-USB.

The micro SIM slot is in a slightly different location, while the Micro-USB is no longer hidden by panel as on the Lumia 800. It is still on the top of the device, however it might make it much easier to create a docking station for the device. There is also a front-facing 1.3-megapixel camera and rear facing camera. Both offer a 28mm focal length.

Inside the phone is powered by a 1.4GHz Qualcomm processor and still comes with the same 8GB of storage.

"LTE is critical at this point in the growth in the US market," said Steve Ballmer, Microsoft's CEO at the launch of the new device in Las Vegas. 

The new phone is expected to be available in the US shortly with pricing being "aggressive". No word on whether the Lumia 900 will be coming to the UK, however with Nokia still keen to push the Lumia 800 we suspect that it won't be any time soon, after all, that would mean updating the company's UK flagship phone within just a couple of months - never a clever idea.
