To assign a status and an icon to a message, invoke
ApplicationMessageFolderRegistry.registerMessageIcon and specify the following as
parameters: a value for the message type for an BlackBerry®device application, a field from the
ApplicationMessage.Status interface as the status argument, and an instance of an
ApplicationIcon.
int MESSAGE_TYPE = 0;
reg.registerMessageIcon( MESSAGE_TYPE, STATUS_NEW, newIcon );

Obtain a reference to the ApplicationMessageFolderRegistry.
ApplicationMessageFolderRegistry reg =
ApplicationMessageFolderRegistry.getInstance();

Register an BlackBerrydevice application folder for each collection of messages.
ReadableList inboxMessages = messages.getInboxMessages(); // collection
