Although Seesmic may have given up their efforts for the BlackBerry platform that doesn't mean there isn't plenty of other developers out there ready to go ahead and fill their void. Tweetcaster has now re-launched their Twitter client for BlackBerry in beta form. Yes, I say re-launched because the app they released before was scrapped in favor of a new UI and additional features such as multiple account support, image uploads and list integration.
You can download the app now for free but it will cost you a Tweet basically promoting the release of the new application. If you're into checking out new Twitter apps, give this one a go and let us know how it's working for you all.
