This is filed under the rumor mill for now, but coolsmartphone.com has an image of a black HTC-made device that resembles the white-Android-based HTC Dream hardware that has been floating around the internet. The Dream has been the code name that is being used for the HTC hardware for Google’s forthcoming Android OS. The black Blackstone may be a fake, but is said to have a big 3.7″ VGA screen, TouchFLO 3D, and a large 8 GB of onboard storage memory.

Even if the Blackstone is a real device, the presence of TouchFLO 3D, the same technology used in current crops of device like the Touch Diamond and Pro, does not necessarily mean that the device will run on Windows Mobile. It could be a refresh of the Android platform as was reported earlier, TouchFLO 3D is built upon open-source codes that may make it easy for HTC to port the user interface to Android and other potential platforms. However, supporting another platform such as Windows Mobile, on the same hardware as the Dream is not out of the question either as Palm had done with its Treo line in which the Palm and Windows Mobile hardware are almost identical.
