I do use the "city" and "state" custom fields in the comment form of my site. But I didn't know (until today) how to show these extra fields in the iOS app when moderating comments. I need to check this fields contents before approving a comment.

I've found the answer and I want to share.

There's an (undocumented, AFAIK) WP filter called xmlrpc_prepare_comment, which is called in the server right before sending the comment data as requested by the iPhone app.

Using this filter in functions.php, I could insert the comment meta right after the comment contents:
```
add_filter('xmlrpc_prepare_comment', 'ios_comment_meta');

function ios_comment_meta($comment_array) {

  $city  = get_comment_meta($comment_array['comment_id'], 'city', true);
  $state = get_comment_meta($comment_array['comment_id'], 'state', true);

  $comment_array['content'] .= "\n\nCity: $city - $state";

  return $comment_array;
}
```
See function _prepare_comment() in file wp-includes/class-wp-xmlrpc-server.php for more info about the $comment_array.
