For anyone with a mobile device, I would recommend downloading the latest in the ongoing connectivity saga, ActiveSync. If you are running Vista, DO NOT install ActiveSync. Vista comes with the Windows Mobile Device Center which is the replacement.
– Although Beta 2 doesn’t allow you to set up partnerships, there is an optional update that you can install (run Windows Update and review optional updates) which will allow you to sync with your device.
– To install the WM5 SDKs you need to disable User Access Control (under user settings in the Control Panel).
