Nokia at its CES press event unveiled its expected first Windows Phone for the US, the Lumia 900. The hardware is just the second phone on the OS with LTE-based 4G and upgrades beyond the Lumia 800 in other ways. A larger 4.3-inch ClearBlack AMOLED gives it a visibly larger view, and a front f2.4 camera joins the eight-megapixel f2.2 camera carrying over to the new model.
