A new additional widget is WeeTwitter by Tyler Flowers. Just go to Cydia, using the same source http://qwertyoruiop.com; when done, go to changes, and install WeeTwitter. You can set Twitter userid and password from Settings.
this doesnt work on iOS 5 Beta as well i installed from Cydia and it is not appearing i went to notifications as well but i cannot see it there as well
