I managed to get my Palm contacts across via Kaddressbook (VCard 3.0). However I had to delete the photographs before it worked. I did this manually on the Vcard stack with a text editor, I don't know if it could be done via KAddressBook or even if that field was accessible there.

I also lost some of the fields (just the manually defined ones I think).

Still working on calendar. I'm hoping someone will make a VERY simple converter for me at some point I got as far as getting the opensync stuff installed on Debian with the GPE and Palm plugins, but no idea what to do with it LOL. When I am a Linux ninja I will try again.
