Oh, the HTC HD2 (aka the Leo) is the gift that keeps on giving. ROMs have been floating around for a while now, and Pocketnow's taken a new build of TouchFLO3D 2.5, ripped out of a Leo ROM, for a spin.

What's new in Build 1919? There's a Twitter tab, e-mails are much more readable without the old envelope-style view. The calendar app continues to improve. Weather and wallpaper are animated. The Footprints tab (remember that?) is around. Facebook and YouTube integration.

Anyhoo, check out the video yourself after the break. We still don't know what build (or version, for that matter) of TouchFLO 3D may be built into the first official releases we see Oct. 6 Super Duper Windows Mobile 6.5 launch day. But let's hope we see some of this included.
