Nokia Lumia 635 launched by Sprint, it's free on contract
Sprint is offering the Lumia 635 for free on contract - which isn’t surprising, since we’re talking about a rather modest smartphone here. Besides all the features included in Windows Phone 8.1, the Lumia 635 offers LTE connectivity, a quad-core 1.2 GHz Snapdragon 400 processor, 512 MB of RAM, 4.5-inch display with 480 x 854 pixels, 5 MP rear camera, and 8 GB of expandable internal memory.
