I've code something like this to get the device os type... the $test will be the string of the user agent

   if (preg_match("/linux/i", $test) && preg_match("/android/i", $test)) {
        $device_type = 'Android';
    } else if (preg_match("/windows phone/i", $test)){
        $device_type = 'Windows Mobile';
    } else if (preg_match("/windows nt/i", $test)){
        $device_type = 'Windows';
    } else if (preg_match("/linux/i", $test)){
        $device_type = 'Linux';
    } else if (preg_match("/macintosh/i", $test)){
        $device_type = 'Macintosh';
    } else if (preg_match("/iphone/i", $test)){
        $device_type = 'iPhone';
    } else if (preg_match("/ipad/i", $test)){
        $device_type = 'iPad';
    }  else if (preg_match("/symbian/i", $test)){
        $device_type = 'Symbian';
    } else if (preg_match("/blackberry/i", $test)){
        $device_type = 'Blackberry';
    } else
        $device_type = 'None';

I think you need to know the pattern and get the keyword. Using WURFL sometimes doesnt get what you want.
