The Nokia Lumia 900 is already at the top of Amazon’s best sellers list for AT&T handsets. The device, which is currently only available for pre-order, will be available in AT&T stores and online beginning on April 8th. We’re not surprised it’s a best seller, however, aside from being an incredible handset the Lumia 900 starts at just $49.99 from Amazon’s website, or half of what AT&T is selling it for. The Lumia 900 offers a 4.3-inch AMOLED ClearBlack touchscreen display, an 8-megapixel Carl Zeiss optics camera, a 1MP front-facing camera and support for AT&T’s fastest 4G LTE network. We’ll be bringing you an unboxing, a review and a video review shortly so stay tuned for plenty of coverage on Nokia’s latest flagship device.
