[Plugin: Mobile WordPress Edition] Error when Exiting the Mobile Edition

When I click Exit the Mobile Edition on an iphone I get these errors:

Warning: Cannot modify header information – headers already sent by (output started at /homepages/45/d289549185/htdocs/acc/wordpress/wp-content/themes/carrington-mobile-1.0.2/functions.php:70) in /homepages/45/d289549185/htdocs/acc/wordpress/wp-content/plugins/wp-mobile.php on line 221
