The First Tweet: Now that you’ve installed UberSocial, of course you want to try it out and send your first tweet! To begin, simply press your menu button on your BlackBerry to bring up the menu list. From there, select “New Tweet”.
This brings you to the compose screen, where you can type in your first tweet. To send, simply press the menu button again and select “Send Tweet”, (or press 'menu' twice)
