After initial connection, now consistently unable to connect to Facebook Service. Receive an authentication Error. I have enabled platform apps via facebook website.
Most of the time this is caused by improper FB login credentials being stored on the phone. I would start first by going into Settings / Applications Settings / Manage Applications - Scroll down to whatever FB App you are using, and click on "CLEAR CACHE" and "CLEAR DATA" ... (I think it's just the CACHE one that stores that login info - so try just that 1st.)
Let us know if this works. Good luck.
