Twikini is a powerful Twitter client for Windows Mobile phones.
Twikini is written in native C++ programming language which makes it a fast app. It supports uploading pictures using TwitPic and different URL shortening services. One cool feature is integration with Windows Media Player by tweeting the song you are listening to plus the artist name.
Bad that Twikini is free for 14 days only as tria, or you can buy it for $4.95 only.
