A few months back Apple and Facebook had a problem over API access in iTunes Ping which led to Apple removing Facebook integration from Ping and then ditching them completely in favor of Twitter in iOS 5. However, it looks like the fight between Facebook and Apple might finally be over.
Last month we had reported that Facebook integration was spotted in iOS 5.1 Beta 3 and it looks like iOS 5.1 might actually have a deeper integration with the social networking website.
Since the problems between Apple and Facebook arose, Facebook started displaying "via mobile" as the update method for their iPhone app. However, it looks like few hours before the iPad 3/iPad HD event, Facebook has started to display the "via Facebook for iPhone" again.
Our editors Parth and Sathya tested out that updates sent from the iPhone/iPod Touch or iPad show the via as seen in the image above. I also tested the same for Android and continued seeing "via mobile".
So will iOS now have Facebook integration like it has for Twitter? Well, our editors think that we should definitely see it during tomorrows announcement. We’ll keep you updated with more information if we come across it and keep you in the loop.
