Answer 1

From the documentation for MFMailCompserViewController:

The MIME type of the specified data. (For example, the MIME type for a JPEG image is image/jpeg.) For a list of valid MIME types, see http://www.iana.org/assignments/media-types/. This parameter must not be nil.

If you look at the link, you can see all the valid MIME types, and text/x-vcard is not listed. I think this means that the Mail composer view controller isn't going to allow you attach a a file with an invalid (in it's opinion) MIME type.
