Facebook on the iPhone

Looks like Facebook may be launching an iPhone specific version of their successful webapp, if you believe the folks over at mashable. Too early to tell if this is a hoax or not in my opinion, but I hope it’s real: I’m no huge Facebook fan, but I am a fan of seeing what other developers come up with for iPhone interfaces.
As a web standards developer, I still have some qualms about going back to old fashioned browser detection, but I’m hoping this time around the industry will keep the the specter of browser code forking under control, and use it as a tool only when really necessary.
