Facebook has (finally!) released its updated iOS app that's been rewritten from the ground-up in native iOS dev code. That means that instead of being HTML5 based (and super-slow,) it's now twice as fast. There are other visual tweaks, but they're relatively subdued. You can scroll faster in the News Feed, pictures are a bit larger, there are nicer animations, and Timeline profile pages can now be viewed on the iPad app. All nice, but make no mistake about it, the star here is the fantastic speed of the app. You can download Facebook 5.0 for your iPhone, iPad, and iPod touch now, for free on the App Store.
