I'm having the same problem, as far as I can tell Facebook made some changes to the site, and that's when this problem occurred. I'm so irritated by this!
ok, so I was b'ing and moaning last night because of the new layout, but I do agree change is good or else we'd still be in the stone ages. It just amazes me that RIM wasn't up to the challenge to get their app synced with the new layout. Surely they knew it was coming. My sister has the iphone and her app is up and kicking, could it be a conspiracy between apple & facebook...lol..anyway, that's just makes me wonder how come that app still works with facebook, but not the blackberry one....things that make you go hmmm...hope RIM gets a fix soon, I'm a facebook addict, and right now i'm tweaking (or twittering)...hahaha...
I'm having the same issue as well. I can't view any comments and my News Feed is blank. I keep receiving an error which reads "There was a problem while communicating with Facebook.". If this has anything to do with the new Facebook layout, I'll be even more annoyed as I can't stand the new layout. It's still filled with bugs and is never up-to-date.
