Leading up to the Consumer Electronics Show this year, Nokia’s first Windows Phone for AT&T was definitely one of the smartphone announcements we were anticipating most anxiously. We were fans of the Lumia 800 when we reviewed it, but when our sources let us know that a bigger handset that maintained the Lumia 800’s design aesthetic would launch soon after CES, the 800 lost its luster. In line with our exclusive report, Nokia’s brand new Lumia 900 features the same unique design and build as the Lumia 800 Nokia launched last year, but there are two key differences that make this smartphone our clear favorite. It includes compatibility with AT&T’s new 4G LTE network, and it packs a larger 4.3-inch ClearBlack AMOLED display. The larger form factor was designed with the U.S. market in mind according to Nokia, and the size of the device is ideal. The Lumia 900’s build is outstanding as well, and Windows Phone 7.5 is beyond smooth thanks to the phone’s 1.4GHz Snapdragon processor. Nokia and AT&T haven’t yet revealed pricing or a launch date, but Nokia did say it will become available in the coming months. We can’t wait to review this gorgeous smartphone but in the mean time, check out our hands-on Lumia 900 photo gallery below.
