I don't have the BES service, and access the internet only through Wi-Fi (yes, T-Mobile has kept me as a customer by offering this service).

The Facebook app they comes preloaded on the phone doesn't allow access. After spending 1.5hours on the phone with T-Mobile/RIM trying to get access to Facebook, they finally figured out how to do it.

You can log-in directly to m.facebook.com. It would be nice if the download app would work, but this is a workable work-around.

The app will work but you have to log in every time because they need to send an SMS text to the phone for authentication.
