Mobile Redirect Blackberry 6.0

I currently use the redirect code below and it works great. However, since Rim has released OS 6.0 I need to update it to work for that browser.  Anyone know how?

<?php

$mobile_browser = '0';

if(preg_match('/(up.browser|up.link|mmp|symbian|smartphone|midp|wap|phone)/i', strtolower($_SERVER['HTTP_USER_AGENT']))) {
$mobile_browser++;
}

if((strpos(strtolower($_SERVER['HTTP_ACCEPT']),'application/vnd.wap.xhtml+xml')>0) or ((isset($_SERVER['HTTP_X_WAP_PROFILE']) or isset($_SERVER['HTTP_PROFILE'])))) {
$mobile_browser++;
} 

$mobile_ua = strtolower(substr($_SERVER['HTTP_USER_AGENT'],0,4));
$mobile_agents = array(
'w3c ','acs-','alav','alca','amoi','audi','avan','benq','bird','blac',
'blaz','brew','cell','cldc','cmd-','dang','doco','eric','hipt','inno',
'ipaq','java','jigs','kddi','keji','leno','lg-c','lg-d','lg-g','lge-',
'maui','maxo','midp','mits','mmef','mobi','mot-','moto','mwbp','nec-',

'wapr','webc','winw','winw','xda','xda-');

if(in_array($mobile_ua,$mobile_agents)) {
$mobile_browser++;
}

if (strpos(strtolower($_SERVER['ALL_HTTP']),'OperaMini')>0) {
$mobile_browser++;
}

if (strpos(strtolower($_SERVER['HTTP_USER_AGENT']),'windows')>0) {
$mobile_browser=0;
}

else {
if($mobile_browser>0) {
    header("Location:  http://www.caffetoscahingham.com/mobile"); /* Redirect browser */
    exit;  /* Make sure that code below does not get executed after redirect. */
} 
} 

?>
