Twitterberry is a mobile client for posting updates to Twitter on BlackBerry phones.

Features:

• all Twitter operations supported
• avatars supported (via Amazon S3 service)
• send photos via TwitPic
• BlackBerry OS 4.2+ required

The Good:

Twitterberry is an excellent mobile client for Twitter. All the usual Twitter operations are supported as are avatars and TwitPic. The graphical display of the UI is much better than many other BlackBerry clients out there. Another great feature is that it runs over the data network and does not require SMS.

The Not-so-Good:

About the only thing we found with Twitterberry that bugged us was actually a good thing: Twitterberry is constantly improving and fixing bugs (now on release 0.8), which means frequent updating may be required. That’s okay: more and better features seem to come with each release.
