Is there a working plugin to auto post to twitter for WP3.1?

as the title says, I’m looking for a plugin that automatically tweets the post I make on the blog. None of these seems to be working on wordpress 3.1

Wp Post to Twitter by MikiUrl (not what I want, current version doesn’t work on 3.1 anyway)
