What is the structure of SMSArchive.dat file?

Its a internal file which is not made to be edited. Why do you need it ?

I'm going to buy Nokia phone and I'll need to convert the database.

PS. Have you ever thought about public API for plug-ins? Every programmer could write their own plug-in to support their phone.

You can export the messages in *.vmg-Format -> this is a Nokia Format
