Just yesterday we posted that the Trillian instant messaging application would be arriving in beta form on BlackBerry soon. I guess the folks at Trillian weren't kidding. If you head on over to the mobile download page for Trillian you'll find that version 18.104.22.168 is now available for download. The beta they are offering up is trial limited, so at some point it will indeed expire but they do not indicate when. Having used it for the past day, I suggest downloading and giving it a try. The list of supported devices can be viewed via the Trillian website and yes, the BlackBerry Storm is supported already. As well as the BlackBerry Pearl 3G although the website does not indicate that model. You can also share your thoughts on it here in the comments or in the CrackBerry forums.
