I've had problems using Bridge with my Curve 8900. Today I downloaded the upgrade for the 8900 through AppWorld. I was able to access my message folder for a few minutes and then a password log-in screen appeared. See attachment.
It doesn't recognize either device passords. My BB I.D. password or the e-mail passwords. I can access my contacts, my calendar but not the messages.
And this doesn't look like the usual BB log-in screen.
