Since Mediawiki 1.20 there is a global DeviceDetection class under includes/mobile. Unfortunately this leads to a problem with the class autoloader. i solved this in my installation by renaming the file and class name of MobileFrontend/DeviceDetection.php and editing the autoloadclasses Array in MobileFrontend.php
