Nokia will try to re-establish itself in the US smartphone market with the introduction of the Windows Phone-powered Lumia 900 early in 2012, according to reports. BGR reports that the Lumia 900 will run the Windows Phone Tango update but will have a similar hardware spec to the Lumia 800 smartphone, which recently went on sale in Europe. However, the 900 will have a larger screen – 4.3 inches compared to the 800’s 3.7 inches.
