I'm really really hoping that the Fremantle browser will be fast and full-featured enough to avoid needing dedicated "clients" for all of the web services and applications like the iPhone and other devices. I would much rather have the "real" Facebook page than a Facebook app. Facebook chat would be nice to integrate into the system along with all of the other chat protocols (it is so great the way everyone duplicates functionality, eh?), but it sounds like that's already being done...
