I have a Cassiopeia EM-500 pocket PC and I wanted to start using it to log on and check email, etc instead of lugging my laptop around everywhere. So, I checked with the manufacturer regarding processor type and compatibility and purchased a SPECTEC WLAN-11b SD card. The problem at hand is the fact that this card does not work with CE 3.0. Does anyone know how I can upgrade my OS to Windows Mobile 2003 Second Edition or Windows Mobile 5.0 Pocket PC; in other words anything that will make this work?? Maybe I'm just not looking hard enough, but I can't seem to find anything :-( Please help!!
