i searched and the only option i managed to figure out, was to use an intermediary step - GMAIL account.
1) export address book from The Bat
2) import in gmail the address book
3) install on BB the google calendar (who has embedded a sync application)
3.1) configure it with gmail user & pass
4) sync the BB with contacts from GMAIL
attention:
in gmail, be sure to have the contacts ordered just right (before you import from the bat)- otherwise you probably would double your contacts on the BB.
I'm also looking for a more direct approach, anyone ?
