Looks like the HTC Radar 4G is the real deal, after all. T-Mobile outed the Windows Phone Mango-sporting handset today, talking up the device's 3.8-inch screen, 1GHz Snapdragon processor, five-megapixel camera (with a devoted camera button) and, of course, the titular 4G speed. No precise date on the thing yet, but the magenta carrier says it should be out in the States before the holidays.
