Sprint is trying to kick off 2012 into high gear with a new winter promotion starting next month. From January 8th through March 10th, new or existing Sprint customers (with an upgrade) can get a Samsung Conquer 4G at the discounted price of $50 but that’s not all — it also comes with a matching Conquer for free. Deals always sound more fun with you throw BOGO into the mix and you could do a lot worse than the Conquer 4G. As a refresher for anyone suddenly interested in the device, the Conquer features a 3.5-inch screen, 1GHz 2nd gen Snapdragon processor, 512MB of RAM and connectivity to Sprint’s 4G WiMax network (where available). Not too shabby for $25 a pop when you buy two.
