HTC EVO Shift 4G headed for a January 9th launch at $150, according to RadioShack leak

HTC's worst kept secret (this side of the Thunderbolt) has popped up online again, this time as part of some RadioShack promo materials, which list its price, launch date, 4G capabilities, and screen size. Earlier indications had this Android slider launching on January 9th at a $150 price point with a two-year contract and now, lo and behold, both data points seem to have been confirmed. $450 is the price for the EVO Shift 4G sans any carrier obligations, though you'll probably want to stick with Sprint to make use of that WiMAX radio contained within. Bring on 2011 already!
