wurflObj available in other modules

Using MobileJoomla version 0.8.1.

In the source 'checkmobile_wurfl.php' the object wurlObj is defined as global. However I can't access it in other modules (e.g. mobilebot.php). Can somebody help?

I found a simple solution for my problem.

I added $wurflObj as a global variable in the class 'plgSystemMobileBot' in the source mobilebot.php. It is now possible to access all $wurflObj methods in other sources.
