Enable Facebook Comments for mobile viewing in Google Blogger?

Is there a way to enable Facebook Comments Box for mobile viewing in Google Blogger? I used these instructions to enable Facebook comments on my blog. It worked out, but it's not showing up in the mobile view. This site discusses how to add a widget to the Blogger Mobile Template. The Facebook Comments Box is not exactly a widget. I imagine there's probably a solution to getting it to appear in the mobile view, similiar to this, but I don't know how to do it. Is there a way to add something like this (mobile='yes') to the plugin code?
