this function I took from counterize mod for wordpress (_http://wordpress.org/extend/plugins/counterizeii/) but its also useful for your mobile sites

[adeii]

Near begining of index.php find $brws line and change to this

$brws = explode(" ",$_SERVER['HTTP_USER_AGENT']);
$ubr = $brws[0];
$uip = getip();
$action = $_GET["action"];
$sid = $_GET["sid"];
$page = $_GET["page"];
$who = $_GET["who"]; 

It works at my place and detect Opera,Nokia,Samsung ... and their versions too (:
