Getting friend email and phone

I am pretty new to facebook development and am trying to accomplish the following requirement for a banking site.

1) I need to get the list of facebook friends of a logged in user and display the same in a drop down box 2) User will select one friend and transfer funds to the same 3) I need to send an email/SMS/private FB message to the selected friend with some details.

I can used the taggable_friends node to get all the friends list and show them in a drop down. Is there any way to accomplish the third point? As far as I have seen, I need the unencrypted facebook id to accomplish this which is not available in any of the graph API nodes.

Can someone please help if this is possible.

Thanks, Aravind
