Hide facebook comments and like buttons in mobile sites

hide the annoying like button and the comments in mobile view
go to ..path_to/wp-content/plugins/facebook/social-plugins
and change this files:
comments.php
social-plugins.php

insert the code

<?php if ( wp_is_mobile() )  {
/* Display mobile specific stuff hardcoded by iYannis.gr*/
} else {
 /* here goes the facebook code */
 ?-->

I hope in the next version be as an option this hack
