Features:

• easy to use UI within the Blackberry platform
• all operations supported (post, @reply, DM)
• avatars supported

The Good:

Blackbird does a good job as a Twitter client for Blackberry. The UI is clean and easy to use and all functions are supported. SMS is avoided, a character countdown is provided, and details about tweets are provided via drilldown.

The Not-so-Good:

Blackbird does everything you could want a Twitter client to do. Our only substantive complaint was the less than attractive appearance that sometimes happens with Blackberry: it works but it isn’t necessarily pretty.

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.
