I'm having a problem, too... it keeps telling me my ID or password is invalid when I try to log in with the correct id and password. This never happened before the upgrade. The new predictive text thingy is crazy annoying on this screen. I wonder if it's part of the problem. Also, sometimes after typing and retyping I finally get in and then I've noticed that the offline messages from the few people who always say "are you there?" to their entire friends list daily (or more often) aren't there anymore. I just don't think it's working right.
