Ideally, the two should be in the same conduit... because the Contacts
application has only minimal differences from the Address Book
application... (OS6 promises to completely gut this from the ground up
with the "Schema" format databases, whee!) 

Ideally, you would check for the version of the user's Palm device,
attempt to open ContactsDb-PAdd and if that fails, open AddressDB.pdb,
and proceed accordingly. 

I'm not sure how the g-p conduits handle it, but they could also query
the version of the Contacts application itself, testing for failure or
success and proceed that way. 

Most of the fields are already reverse-engineered in the pilot-link
headers for the Contacts application, so you might start there if you
get a bit lost decoding them.
