I have a 9700, my carrier is Rogers Wireless. The OS is working fine except when I go to social feed options, I only see Twitter and BBM check boxes. I removed the .vendor when I installed and followed service books guide. I have Twitter, FB and Buddy Guard installed other then Task, Memopad, Calculator installed. I also reinstalled Facebook already. Any ideas? or could this just be a bug?.. I haven't came across any bugs yet. I'm pretty sure FB works though other people are reporting it working so whats up?
I had this same problem and searched the crackberry forums for an answer. I saw a post in the Torch forum that said to uninstall facebook and then go to mobile.blackberry.com and download and install it from there.
