I am wondering if your facebook module will correctly integrate the right birthday date into jomsocial and data fields. If a user allows birthdays to be shared, I am looking for something that grabs the right birthdate. Currently, the solutions I am using do not produce the right birthday - usually default to the first of the month, although some have the right year.
Nope, that's not there yet. We've started to get this exact request recently, and date importing (for birthdays and other things) will be part of the 3.1 release due this month.
We'll try to post back here when the release is out, but would recommend following our blog or twitter account for more information on it's release!
