title: In Rails, how to make :mobile views to fallback default views when not found?
body: <p>This question is a follow up to my previous unanswered question: <a href="https://stackoverflow.com/questions/10526214/actionviewmissingtemplate-missing-template-trying-to-render-nonexistent-mob/10526344#comment13870709_10526344">ActionView::MissingTemplate: Missing template (Trying to render nonexistent :mobile format )</a></p>
  
  <p>Since doesn't seem to be a Rails approach consensus with this, Is there any way that when accessing from a mobile device to render default <code>:html</code> when <code>:mobile</code> format is not available? (If a <code>:mobile</code> view is present should have priority over those who are not mobile formatted). </p>
