Twitter for BlackBerry v184.108.40.206 has arrived! But not quite yet in the BlackBerry App World. If you weren't as fortunate as me to have your BlackBerry pop up with a little notice that Twitter would be unavailable to you until you upgraded, here's what's going to happen: either one of the BBOS bloggers are going to update this article post as soon as it is available for us to link to you, or you can continue refreshing App World. Your pick. Also along with the link to upgrade will be the change log, of course.
