No I do not. I do know that the Windows Phone version communicated directly with Facebook due to network traces I had done back then. It did not use an intermediary. I could see some devices using an intermediary, especially for under powered and "dumb" phones where they may have made a simplified web app that would be usable on their platforms where as the actual Facebook web app would not have been. Think flip phones that had Facebook integration.

I don't know if that happened or not, but the way this article reads is very misleading and several of the vendors that they listed did not actually have access to the data.
