Hey guys

For a company website I have a .com and a .mobi domain. The content differs a bit as the content on .mobi is more straight forward and to the point for mobile users.

My .com ranks well. However, the problem I have is when I google the keywords that I targeted, from a mobile device, I get the .com in search resluts not the .mobi. Is there a way I can tell google that the .mobi is that specific site's mobile version of the site and that it should favor the .mobi above the .com whenver a user googles from a mobile device?
