Facebook for iPhone users now have access to all the new features for in the official Facebook for iPad app that launched this morning. Now available in the App Store, the 4.0 update includes a major redesign of the navigation system that facilitates quick switching between features, and the ability to access third-party mobile apps.
The update to Facebook for iPhone’s 91 million monthly active users and 51 million daily active users gives developers a huge new distribution channel for their mobile web and iPhone apps.
One of the worst things about the old Facebook for iPhone app was the grid screen navigation. If users wanted to switch between in-house Facebook apps such as the news feed, Photos, Messages, and notifications, they had to exit their currently used app to the grid screen, then dive back into another app.
