I just updated to 4.0 and jailbroke it. at first Facebook app was working like normal, then minutes later it seems like it loses it's internet connection telling me i'm offline and not loading the news feed, while stuff like safari is still working. i re-installed it but now it won't even let me log on, i get "Login Failed Unable to connect to Facebook. Please try again later." soo... what could I do? I don't really know what the problem is.
