Device Detection Working, Theme Switching Not

For my site, I am switching users to my mobile subdomain based on device detection. And all of that is working. However, when users are seeing the mobile version of the site, they are still seeing the main theme's home page, as well as the node I created specifically for mobile users. Essentially two home pages stacked on top of each other, the top is the desktop, the bottom is the mobile-specific page that should be the home page for the mobile users.

I have configured everything correctly (Switch Theme based on URL) but there's a portion in the Theming Configuration instructions that says, "In order to use this functionality you will have to manually create a second *.info file in your theme directory." Can someone give me some insight into what that might be? And any other help in solving my issue would be appreciated.
