Facebook is releasing a faster version of its popular iPhone app, addressing complains among owners of Apple's top-pselling device. Rather than adding a slew of new features, the company says it has rebuilt it from scratch to make it speedier and less clunky.

At a recent demonstration at the company's Menlo Park, Calif., headquarters, the new app loaded about twice New Facebook as fast as the older version on the iPhone. Photos and comments also load faster, and users can now "like" comments on photos.
