I successfully installed the application, but when I try to log in, it just brings me back to the log in screen to re-enter my email and password. Am I not doing something right?--or is the service down?

Nah ....... the service is not down ......... the app just sucks! I had a lot of problems with it, but mind you I was able to get past the login. I just go directly to the mobile site.

Open your BB Browser or MiniOpera and go to hxxp://m.facebook.com This way you can remove the app and free up memory too! Replace xx with tt

Don't forget to bookmark it!
