Digital renderings of what's supposed to be an upcoming HTC Windows Mobile (WM) device have surfaced. This is the HTC Firestone, a possible successor to the HTC Touch HD. A WM6.5 screenshot is found on the display, which apparently measures 3.6 inches diagonally with a resolution of 800x480 pixels. The Touch HD has a larger 3.8-inch screen in comparison.
Another interesting specification is the 600MHz Qualcomm processor, which is faster than the 528MHz MSM7200 chip on many other HTC devices today. WM6.5 isn't due for another few months, so we'll just have to wait and see if this Firestone rumor turns out to be accurate.
