This one's a bit of a mystery, but it's certainly a tantalizing one: Haykuro of xdadevelopers fame has posted video of what purports to be the Android build off of HTC's upcoming Hero device. What's special about it is a reworked interface, which shows a lot of polish from icons to built-in apps to general interface elements... and maybe just a bit of TouchFLO flair. There are also new features like a login / logout menu for "social networks" in the settings menu. While the device lists the firmware as 1.5, there's a small possibility that some of this new look and feel could be headed for Android 2.0 "Donut," or perhaps HTC just feels like it needs to diverge from the pack a bit now that other manufacturers are starting to drop their own Android handsets. Check out the incredibly epic video after the break.
