The Facebook app at this time is not a very good app, IMO. There is a Version 2.0 coming out soon that will fix some bugs. Right now, your problem is the FB app. Remove the app from your device, pull the battery and allow it to reboot, and make sure every thing is back to normal without FB. If it is, then try to reinstall the FB app. Either way, the error messages are because of the FB app. Hopefully, 2.0 will address those problems.
I've had these issues for a few months now and heres the solution...
You have to "connect"/register the Blackberry all over again each time it does this...
Options>>Device>>Advanced System Settings>>Host Routing Table>>(Blackberry Key: Register Now).
Thanks for your response. I hope it works for the original poster in this thread. Hopefully, we will hear back from them and will know if it works for them.
Ps Kudos points to you for helping. Thanks
Thanks for all the replies team members. As a last resort, you have the option to go back to the 5.0 software on your blackberry if you like. You can do so by using the application loader in blackberry desktop manager. Just another option.
