Tweaked wp_is_mobile that does a separate check for iPad

hip_is_mobile.php

<?php 
function hip_is_mobile() {
    
	if( strpos( $_SERVER['HTTP_USER_AGENT'], 'iPad' ) ) {
		$cookie = $_COOKIE['is_mobile'];
		if( $cookie == 'yes' ) 
			return true;
		else
			return false;
	} else {
		return wp_is_mobile();
	}
}
