There IS a way to view Facebook on landscape mode!
Go to the Safari browser and access Facebook from there. Bookmark it and use it for your browsing instead of through the Facebook application. Quite the hassle, I know. That's Facebook's decision, not Apple's. Certainly, they have heard us scream about this for years now but, for some reason, they have decided to turn a deaf ear to us. WHY??? Does anyone know?
If anyone knows of a better solution to this while using the Facebook app, please, TELL US! If you have to jailbreak the phone to do it, let us know how that can be done also. THANKS!
