My friend is always updating his facebook status via twitter, not sure why he can't just log in to facebook and update but anyways...his is working fine. I don't have a twitter because I think it's useless if you have facebook, but all my acquaintances who have both haven't complained. If possible, you may want to try and sever your old facebook account from twitter, then reconnect..otherwise you may to just create a new twitter account as well. Why did you want to get a new facebook account anyways?
