One Mobile Site to Serve Thousands of Phones

This post details a major upgrade to m.facebook.com, unifying the mobile web experience by moving from multiple device-specific mobile sites (m.facebook.com and touch.facebook.com) to a single, adaptive framework. This new approach uses XHP, Javelin, and WURFL to dynamically serve the best possible experience for thousands of different mobile devices, enabling faster feature development and consistent feature availability across all mobile platforms.
