extended Facebook implementation to also populate the DOB & gender fields in the customer account when signing up via FB login

This seemed quite simple, I hope I haven't overlooked anything, but it's working fine for me.

I tried that, and my date of birth wasn't well recognized. Facebook printed it in the american standard (Month Day Year) and Magento processed it in the (Day Month Year) standard.
