I sync my T600 with a Mac through isync, using ical and Mac address book.

A few weeks ago, I had an isync corruption that forced me to overwrite the handheld data with data from the mac. In this process, all my category info was lost (since mac address book doesn't support categories). I can manually put all my contacts back into their categories on the handheld, but it will take a while. Is there a faster way on the desktop -- which doesn't inlcude disabling isync and using palm desktop -- as that sounds like a messy solution.
