A unified messaging interface and associated methods that enables mobile communication device users to initiate the creation of a message for a recipient without being required to explicitly specify the type of message that is to be created. The mobile communication device supports multiple message types, such as voice, text, and picture messages. The user begins providing message content to the communication device by, for example, speaking, entering text, or clicking a shutter of a camera. The unified messaging interface detects the nature of the content and creates a corresponding type of message. The user can indicate a desire to create and send a message by performing "one-click" action. The one-click action is an operation performed on the device that can be instantiated as a single button-press on the keypad; selection of a single soft key by depressing a button on the keypad or touching the screen of the device; or issuance of a single voice command.
