Technology blog Mashable has reasons to believe that Facebook will finally reveal their official app for the iPad at the Apple iPhone 5 event scheduled on October 4. The Facebook iPad app was leaked earlier this year.
In addition to the iPad app, Facebook is also expected to release a revamped version of its iPhone app and may unveil an HTML5-based mobile app marketplace.
The delay on the app is due to some “relationship issues” between Apple & Facebook. The Facebook iPad app is believed to have been completed in May.
There’s also rumors that Facebook was supposed to be integrated into iOS, but disagreements on both sides eventually led to Apple integrating Twitter into iOS 5.
