WM6.5.3 post UI changes (probably COM3/COM4/COM5 variants as well, though that depends on how well they run)
With all the configurations, the SYS will have things available in marketplace removed, and the XIP will be tweaked for best performance.
Full - Has all the HTC programs/files with things like sample images removed
