ActiveSync 4.0, when its released by Microsoft, will no longer support ActiveSync over 802.11b or wired Ethernet to a stand-alone PC, ie. a non-Exchange environment like most home users run. Fortunately, users of Windows Mobile 2003 SE, Windows Mobile 2003 and PocketPC 2002 OS devices will not need to upgrade to AS 4.0. Users of devices running the newer Windows Mobile 5 OS will be required to use AS 4.0 however.
