One of the most important OOTB features of ME is the Base Plugin. It provides comprehensive access to SharePoint lists, document libraries, discussion boards, and search. These lists and libraries are configurable via the Mobile Entree Configuration page that is available to site administrators from the Site Actions menu.

From the configuration page you can expose select lists and views to your mobile users.

This provides an easy and intuitive way to give instant mobile access to your SharePoint content without doing any custom development. The last few images here are from the Base Plugin rendered on an iPhone.
