For those recently Windows Mobile defectors, keep in mind that you will need to install the Splash ID Blackberry Desktop in lieu of your existing version as this will then allow you to synchronize via BB Desktop Manager (Synchronize - Configure - Add Ins).
I have also used this application for years, as I actually started with the Palm version and then migrated into Windows Mobile, iPod Touch and now my Blackberry. I pretty much hit them all with the exception of Nokia and Pocket PC and I also don't work for the company, but swear by this application as I have several hundred entries!!
