Parse error : unexpected T_STRING functions.php

Hi, i am seeing the following message when i log on to my website http://www.smilespreaders.org –

Parse error: syntax error, unexpected T_STRING in /home/content/69/7786769/html/smilespreaders/wp-includes/functions.php on line 3742

Any assistance will be appreciated.

Line 3742 corresponds to }turn bool true|false )

The rest of the code –

/**
 * Test if the current device has the capability to upload files.
 *
 * @since 3.4.0
 * @access private
 *
 * @return bool true|false
 */

function _device_can_upload() {
	if ( ! wp_is_mobile() )
		return true;

	$ua = $_SERVER['HTTP_USER_AGENT'];

	if ( strpos($ua, 'iPhone') !== false
		|| strpos($ua, 'iPad') !== false
		|| strpos($ua, 'iPod') !== false ) {
			return preg_match( '#OS ([\d_]+) like Mac OS X#', $ua, $version ) && version_compare( $version[1], '6', '>=' );
	} else {
		return true;
	}
}turn bool true|false
