The switch from HTML5 to a native app is definitely showing improved performance and now allows the app to tap into other features in iOS’ SDK. I’m still impressed with the architecture of developing a web app within a native frame like they did in the previous version (especially useful for updating apps across browsers/platforms with less effort). Users don’t have to update the app as often (pushes can be made server-side without the need for Apple’s app approval process). They’ve also added a few “fallback” methods to reduce the need to continuously update the app when new features/changes are required. But this update is definitely much more advantageous for Facebook’s mobile users.
