You will search for custom mobile redirection in your favorite search engine and get to How to: Customize the Mobile Home Page Through Redirection this will help you to change redirection within mobile pages (aka application pages), but not to publishing pages. There you can understand the current process (even an old reference to the previous system), however I would recommend you to read the SPMobileWebUrlRedirect Class (Remarks section). This system won't work as it appends ?Mobile=1 to every page and this parameter redirects to Collaboration mobile lists views.

Those are nice samples, but you should follow approved & officials steps ;)
