About social networking applications
You can use social networking applications on your BlackBerry® device to stay connected with your social networking contacts. Depending on the social networking application, you might be able to send messages, share pictures, change your status, and more.
You can download social networking applications for your BlackBerry device from the BlackBerry App World™ storefront. You must have a wireless service data plan to use these applications. Depending on your wireless service provider or organization, some applications or features might not be supported.
