Me, I went slightly the other route: IntelliLink.
Basically, I had my existing program dump my phone book to a Tab Seperated ASCII file. Then I used Intellilink to dump it to the Zoomer.
The only problem I had was that the original program (Delrina Daily Planner 3.0) handled Company contacts a little differently than Personal contacts. The result was that I had to update a handfull of records that got dumped under '*'.
