Simple Mobile Redirect

To configure Simple Mobile Redirect go to Administer / Site Configuration
Open the Settings section and input URLs as follows:

For the non-mobile site:
Leave the default which is - /
I'm not sure what the effect of other input might be.

For some or all of the device redirects, input the URL in the format: http://example.com

The instructions at the top of the page say:

Link back to /?nomobi=true to set a cookie to stay on the full version of the site.
Link to /clearsimplemobileredirect to clear the cookie and redirect to Mobile sites.

I am not sure exactly what these instructions mean or how to implement them

Without installing any of the patches listed at https://drupal.org/node/1619732 mobile devices are redirected just once and then go to non-mobile site until the cookie expires.
