This is easy - no special magic here.
Just import the anniversaries to iCal and synchronize the iCal calendars with your iPhone the way you always do.
That's it. You are done.
Note: For the anniversaries to look best on the iPhone, choose an event title optimized for iPhone: In the BirthdayScanner X main screen, open
How should the events look like, select
Short (optimized for iPhone) .
