I have been using Twitter for some time now. All my twittering is usually done via some twitter client on my Mac while I am stationary at home or at work. I’ve been looking for an efficient twitter client for my Samsung Blackjack v.1 smart phone (Windows Mobile 6) in order to get twitter updates while on the go. I stumbled on Tiny Twitter, which is built to run on Windows Mobile and Pocket PC smart phones, and most blackberries and other java enabled devices out there. It has built in support for TwitPic, and also supports user timeline follow, direct messages, updates, retweet, and uses your Internet connection, so no SMS every time someone updates.

The application is free, so try it! Just go to http://www.tinytwitter.com/m/ from your mobile phone's browser, download and install the .CAB file, and voila!
