We heard about Twitter for BlackBerry v2.0 earlier this week at BlackBerry World , and now version 2 Beta is available in the BlackBerry Beta Zone.
RIM is taking a different approach and will offer more frequent beta versions with features added and the current version 2 of the Twitter app brings a simplified navigation bar at the top. It combines the Search, Find People
, and Popular Topics screens into a new Single Search Screen in addition to integrating with the Universal Search feature. There's also a new Black Chrome color scheme and the Compose Tweet button is accessible and allows you to tweet from anywhere in the app.
