A BlackBerry variant of Seesmic has just been released and is now available to download for free. It is well featured and could well challenge the likes of TweetGenius.

“Seesmic for BlackBerry groups all your Twitter timelines into one simple application. Whether you want to scroll through your friends timeline, check on a saved search, view a list or want to find a private conversation with a friend, everything is one click away from the main menu.

We took our cues from the simple, clean-yet-powerful interface the native BlackBerry email application enjoys and developed a similar experience for your twitter stream. Our goal has been to show more tweets on the screen then any other twitter application for BlackBerry.

While it is running in the background, Seesmic for BlackBerry will alert you to received Direct Messages and @Replies that require your attention. This is done using the familiar system-wide icon notification bar that alerts you to new mail, sms messages and voicemails.”
