I can't imagine that the cell phone carrier would be responsible. I think it's some issue with the Windows Phone 7.5 OS talking with Facebook correctly about notifications. I don't know whether the problem is on MS's side or FB's side, but it seems to me the problem has got to be there. It's not like I ever get false notifications in the mail app or any other app, so it can't be the carrier's fault (if it was the carrier's fault, it wouldn't be tile-specific).
My suspicion is that it's FB's fault. FB in general has been very buggy recently--the private messaging feature in particular springs to mind (they don't always go through immediately, and you don't always get notifications when they do go through). Whereas other Windows Phone 7.5 apps are so polished (the mail app and its notifications work perfectly), it seems unlikely that Microsoft would just completely screw up notifications for this one tile and never do anything about it.
