Mobile | Standard sites URL

How can I add the mobile URL to my main site? i added m.demo.com and it just kicks me back to the standard site after I told the mobile template I wanted standard.

Similarly, Im wondering if there is a php link, or href i can use if i want to link to the "standard site" from the mobile template instead of having it in the footer.

Thanks

To disable redirect between mobile domains, just set in MobileJoomla settings "Redirect to domain: No" for all of them.
