use PCC try to repair. Make sure that your internet connection have no problem.
I hope you did the factory reset version of the update. If not, you should seriously consider doing that - my own experience with the JB update hasn't been bad at all.
Obviously, this means you'll lose your stuff (unless you back it up first), but it's well worth it considering your current situation.
