From Fsckin with Linux:
mitter is another simple Twitter client. Much like gtwitter, it downloads avatar pictures to display inline with updates in your personal timeline. I couldn’t get the status update function to work properly, and emailed the author. He was kind enough to let me know that mitter is intended to be a Maemo application that will eventually run on Nokia smartphones. He actually updated the code and had me test out the latest version which fixed the problem I was having. I also happen to be the 2nd user he is aware of using the application. :) He’s got some good features coming soon like auto-updating and is open to suggestions from users.
