i tried it on Windows Mobile 5.0 Smartphone, and not surprisingly, it doesn't work too well. it installs fine, but when running keeps generating exceptions in device.exe and gwes.exe. also, the UI does not work well because it's designed for Pocket PC. again, no surprise, but in case any smartphone users are tempted to try it, consider yourself warned.
kudos to whoever got it to work on a Pocket PC though!
