The guys over at Pocketnow discovered a YouTube video that offers a preview of HTC Sense 2.1 running on the HTC Hero. Most of the video is fairly mundane but one notable feature is the support for multitouch. A pinch gesture was used in the video to show off a new homescreen preview which allows you to view all your homescreens as thumbnails and switch to any widgetized homescreen with a single tap. The full video, complete with a modern musical score, is after the break.
