Get it while it’s hot from the download center. The content in my original overview of the Windows Mobile 6.5.3 SDK is still accurate. However the installation issues have been resolved and there is a bunch of things (like the help files and the Map Framework sample) are now installed correctly. The installation of the DTK should not affect any of the existing emulator images you have installed. Stay tuned for more information on what’s in the DTK.
