I got a replacement blackberry and used the device switch wizard to transfer my stuff from my old 8520 to my new 8520. Well, my facebook app says "We cannot reach the Facebook server at this time. Please try again later. (100)" and my Twitter app says "Twitter services are currently unavailable."
I can't figure it out. All the permissions are set to Allow. The firewall is off.
I have just tried updating both my twitter and facebook and both worked for me. I would recommend uninstalling those applications and reinstalling them. If that doesn't work - please let us know! Then we could move on to other things to try and help you out.
I have a new 9800 and face the same problem with Facebook and twitter that justin had. Tried the solutions suggested but could not succeed. Pl suggest something else
