Magento

Hi There

As per instructions written here: http://www.magentocommerce.com/magento-connect/Magento+Core/extension/4457/magento_mobile
I installed the extension.
The key I used is: magento-core/Magento_Mobile-1.4.1.0.19 because my magento version is 1.4.1
I used Connect Manager to install which I think is the automatic installation, it said in the end that installed successfully. However when I went back to my admin panel I dont see the mobile Tab?
I logged off and logged in, cleared cache but still dont see the tab. anything i am missing here?

Any help is appreciated.

Thanks.
