FCC approves an HTC Touch Cruise with North American 3G -- but why?

With the dull roar of frenzied anticipation (okay, that might be over the top, but you know what we mean) surrounding the launch of the Touch Diamond in all its variants around the globe, why would HTC take a step back in time to get one of its older models approved in a new flavor? Don't get us wrong -- for its day, the Touch Cruise was one of the hottest Windows Mobile devices going -- but the Touch Diamond has seriously muted an overwhelming majority of the WinMo kit out there, including much of HTC's older lineup. Put head to head, the VGA display and TouchFLO 3D alone are enough to make sure the newer handset spanks the Polaris, but for whatever reason, Mr. Chou and his gang saw fit to repurpose it with HSDPA 850 / 1900 and send it through an FCC lab. We're not sure whether this will end up on a carrier anywhere, but with the front-facing cam, we'd probably rule out AT&T off the bat.

Update: Touche, there's a Touch Cruise already in circulation with 850 / 1900 3G -- but the question remains, why was this just approved? Thanks, everybody!
