I am using Drupal for Facebook and post to Facebook module on my Drupal 7.15 site.

When I view the site from a desktop or laptop the connect now button is available when I am not logged in.
When I view the site from any mobile the button is not visible.
I tried 4 to 5 mobile using diff OS, what could be the reason for this.

I have one query hope you can help.
I have a technical support website and it contains link to download files for drivers and some freewares.
I am using link image and pasted the link so that when user will click on the image they will be directed to the other website to download the file.
This is available for both registered and anonymous users.
I want to hide the link and when a user clicks on like us on Facebook only then the button should be available.
It might sound a it tricky but it is usefull to gain attraction
