OpenBeak (formerly TwitterBerry) is probably one of the best known Twitter clients for BlackBerry. When Twitter first started its monumental rise, TwitterBerry was one of the few clients available for BlackBerry, and everyone who was jumping on the Twitter wagon got in on the action. New clients began to show up, and TwitterBerry quickly fell to the back of the pack. It didn't totally go away, and now rebranded OpenBeak, it still hopes to capture users with its simple features and ease of use. Take a look at the video above for a quick overview of OpenBeak's features (or lack of) and see how it compares to the other clients in our Ultimate Twitter Client Roundup.
