You might be misled reading Handheld PC forums for ActiveSync advice for a Pocket PC. We recommend ActiveSync 3.8 here because it provides the best support for Handheld PCs
(the devices with the core Windows CE desktop screen and, usually, a built-in QWERTY keyboard
). It is less likely to make a difference with a Windows Mobile 6 device like your iPAQ. You might want to check a forum that specializes in Pocket PCs, such as Pocket PC Thoughts.
