Ok i was just given a Cassiopeia E-125 as a gift. Its a Pocket PC with a 150mhz CPU, 32mb internal mem, a 240x320 res, 65million color, etc. Now the OS on it is Microsft Windows Pocket PC 2000 (Microsoft Windows CE 3.0)! Now the latest is Pocket PC 2003. I wanted to know if i could upgrade my pocket pc to the latest OS, if not how far can i upgrade it to. I've been looking around online for the answer, but i only found info on the Pocket PC 2002, which SOME of the Pocket PC 2002's could be upgraded to the 2003! I appreciate the help!
