I checked the source code for this skin object -

        /// <summary>         /// Get Url for the equivalent full site based on the current page of the mobile site         /// </summary>         /// <returns>string - Empty if redirection rules are not defined or no match found</returns>         public string GetFullSiteUrl()         {             var portalSettings = PortalController.GetCurrentPortalSettings();             if (portalSettings != null && portalSettings.ActiveTab != null)             {                 string fullSiteUrl = GetFullSiteUrl(portalSettings.PortalId, portalSettings.ActiveTab.TabID);                 if (!string.IsNullOrEmpty(fullSiteUrl) && string.Compare(fullSiteUrl, portalSettings.ActiveTab.FullUrl, true, CultureInfo.InvariantCulture) != 0)                 {                                         return fullSiteUrl;                 }             }             return string.Empty;          }

This sounds wrong to me - the Active Tab is my mobile page and I have no rules set up for it, so I think it will always return empty.I have a single rule on my normal home page (NOT the active tab) which redirects mobile requests to this mobile page. 

Do I have to set up a rule on the page where the LinkToFullSite is shown in order for this to work?
