Earlier this month, the World Wide Web Consortium announced the availability of the W3C mobileOK checker, a free service that performs various tests on a Web page to help you determine its level of mobile-friendliness.
According to W3C Director Tim Berners-Lee, mobileOK checker builds on the suite of quality assurance tools already offered by W3C and "does a nice job helping you improve your content one step at a time."
To help ensure the best user experience across a variety of mobile devices, the Mobile Web Best Practices Working Group defined a set of recommended guidelines to follow when creating Web documents: the Mobile Web Best Practices 1.0 specification.
The checker is at: http://validator.w3.org/mobile/
