Connect and get things done
Give people everywhere the power to connect, collaborate, and do what's most important to them. It's all about productive action.
The essence of a BlackBerry experience is communication. Think about communication broadly and how your application can help people connect with others easily. Brainstorm ways to streamline the experience and keep users in your application, so that they don't have to switch applications to communicate with others. For example, your application can integrate with BBM, the phone, or text messaging.
Find a way to integrate that makes sense for your application. Always keep the user goals in mind.
