Synchronization Software
With the Handheld PC 1.0, the first Windows CE based device, Microsoft
shipped H/PC Explorer 1.0. Windows CE Services replaced
H/PC Explorer with release 2.0 of the Handheld PC. Windows
CE Services 2.x and ActiveSync 3.0, 3.1, and 3.5 are compatible with all
Windows CE 2.x and 3.x devices. ActiveSync 3.6 only supports Windows
CE 2.11 and 3.x devices. Each newer release adds additional
capabilities for synchronization - Windows CE Services 2.1 added Mobile
Channels, 2.2 adds Pocket Access.
ActiveSync 3.0 eliminated the need for RAS to be installed.
ActiveSync 3.1 expands on
ActiveSync 3.0 by adding
synchronization of notes into Outlook, built-in AvantGo, Favorites and
Access Table Synchronization. ActiveSync 3.1 works with all Windows CE
2.0 or later PC Companions.
ActiveSync 3.5 adds support for the Pocket PC 2002, Inbox folder sync,
and network pass through (Pocket PC 2002 devices only). ActiveSync 3.5
works for all Windows CE 2.0 or later devices. ActiveSync 3.6 adds support
for the Smartphone. ActiveSync 3.7 added support for the Windows
Mobile 2003 Phone Edition. You can download both H/PC Explorer and latest
version of ActiveSync from
Microsoft's website.
