The mobile view of the SharePoint site/sub site can be accessed by adding 'm' after the site/sub site in the url. 1. The mobile home page has a short URL with an "m" folder appended to the end of the regular URL (for example, http://Site URL/m/) that redirects the request to the mobile view's default.aspx page 2. The default.aspx page then redirects the user to the actual home page (http://site or sub site/_layouts/mobile), according to the current site definition type 3. To access this, 'mobile view' needs to be activated for site/sub site. For activation details follow the link.
