Ronen pointed out yesterday that Google talk has been updated to version 2.1.33. I'm not really a GTalk user (though I seem to be on every other messenger app), but the early comments point to some minor, yet welcomed improvements:
And of course, it's still free. To download the updated Google Talk 2.1.33, just head to www.blackberry.com/googletalk. If I missed any of the improvements feel free to post them in the comments. We also have a thread in the forums for it!
