The latest version of Twitter for legacy BlackBerry devices has made its way out of the Beta Zone. You can now find v4.3.0.18 of Twitter in BlackBerry World. This version lets you see more photos and view image galleries. It also gives you the ability to go full screen and adds a connect tab to show you followers, mentions, and retweets in one place. Search has also been improved to include more relevant information along with users to follow.
