Thank you for your response. The Cingular 2125 does run Windows Mobile 5.0
and I have downloaded and am running the most recent version of WMDC and am
getting the results and error message I described in my original post. Any
suggestions as to what the problem might be or what I might try? Thanks.

I believe the Cingular 2125 runs Windows Mobile 5.0. To sync a Windows
Mobile device with a Windows Vista PC, you need to use Windows Mobile Device
Center on the PC.

Microsoft replaced ActiveSync with Windows Mobile Device Center, an improved
version of the software for use with computers running Windows Vista. You
must use this new program to sync your Windows Mobile device in Windows
Vista. The first time you plug a Windows Mobile device into a computer that
is connected to the Internet and running Windows Vista, Windows Mobile
Device Center should automatically download and install on the computer.
After you set up your device to sync in Windows Mobile Device Center, the
sync results will appear in Sync Center.

Note: Windows Mobile Device Center does not run on Windows Mobile devices.
Windows Mobile devices still use ActiveSync.
