Aston just let me know that eBuddy has released a beta client of their IM software for all of the 8000 series BlackBerry devices. The best part is that it is free. I have not had a chance to try it myself but it looks pretty cool. It is compatible with AIM, MSN, & Yahoo Messenger all in one buddy list. Oh by the way the funny mascot reads all your Instant Messages.
Let me know what you think if you install it or send some screenshots over
