Force update accountdetails on checkout (Facebook Connect)

Hello i would like some help with the following:

I'm using Facebook Connect VQ MOD & Post your Products on Customers Facebook Wall what is working well for login and register but it don't retrieve the user adres details. And on checkout the user isn't prompt to give this information. Ofcourse this information is important because otherwise i'm not able to send the bought goods.

Is there away to retrieve this data on checkout? Maybe codewise? or Onepage checkout?

Thanks in advance!
