It became an anticipated handset almost as soon as the recent Nokia World event came to an end, but now it looks like the Nokia Lumia 900 will be here fairly soon. As soon as next month in fact.The Nokia Lumia 900 is presumably the flagship phone hinted at by the head of Nokia France. In fact, just ahead of the launch of the Nokia Lumia 800, a handset called the Nokia 900 was detailed – and those details aren't a million miles away from the ones being touted by BGR.According to that site, the Lumia 900 will be here in early 2012, with a launch just after the CES event. It's not a million miles away from the Lumia 800, but will have a bigger 4.3-inch ClearBlack AMOLED display, as well as a 1.4GHz processor and an 8-megapixel camera. However, just as interesting is that the operating system will change to Windows Phone Tango. Details of that aren't really set in stone yet, but the limited information in the open so far suggests an operating system that bridges the gap before an all-new Windows, with new features such as NFC support and the ability to run on lesser hardware. Not really important on the Lumia 900, but that could also open the door for a more entry-level Windows Phone, which may also launch in early 2012.All will be revealed soon. In fact, once Christmas is out of the way, it will be just a few weeks away.
