How to give mobile version link on the standard website ?

I have not implemented seperate subdomains on my Joomla! website for mobile and standard versions. In the default mobile templates, I can see a "Standard version" option to switch to the "Desktop-URL"...but on the desktop (non-mobile) version I want a similar option for switching back to mobile version. What link should I put in ?
Typically to switch back to the mobile version, we need to delete cache/cookies first....can this be done on clicking the link itself ? Or is there any other workaround ??
Thanks in anticipation !!

I have exactly the same question.

Currently the only way is to use "Select Markup" module, but I hope in the future we will introduce more simple way.
