The Facebook iPad app is among the most requested apps of all time. And it's finally available. The Palo Alto-based social network unveiled its official app for the device, the most popular tablet on the market. The new app promises "a new way to experience Facebook," featuring a better photo and video viewing experience, easier navigation and Facebook games among other things. According to a former Facebook engineer, the Facebook iPad app had been feature complete since May, but the company decided against releasing it for the past five months. He left Facebook for Google out of frustration over the delay. Mashable earlier published a revelation about the relationship between Apple and Facebook that may have resulted in the delay. It turns out the companies weren't on the best of terms after Ping, Apple's music social network, failed to integrate with Facebook. It didn't get any better when Steve Jobs learned about Facebook's intention to release an app for the now-defunct Hewlett-Packard TouchPad -- at least not until CEO Mark Zuckerberg vowed to get the app pulled. Then there were rumors of a reunion, with suggestions that the companies then were working together on Facebook’s HTML 5 mobile app platform, also known as Project Spartan. Some even thought Facebook would launch its iPad app during Apple's "Let's Talk iPhone" event. Alas, that didn't happen. So, a week after the event, Facebook released the app on its own, uneventfully. Download the official Facebook iPad app in the App Store.
