How do i design my gallery for mobile phones.

[twiter]

I get an email from google and it says that after 21Th of April, the websites which are for competible with mobile phones are valuable in search results.
It is very important for SEO.

I find this from topics;

Code: [Select]

//--- Browserweiche für iPhone-Webseite ---
 if(strstr($_SERVER['HTTP_USER_AGENT'],'iPhone'))
    {
    echo '<script type="text/javascript">';
    echo 'window.location.href = "http://m.sitecom/index.php";';
    echo '</script>';
    }
But after that how can create mobile template; without mobilezer websites?
