A method for handling messages between wireless devices in a network, includes: receiving a message for a device application by a dispatcher application on a receiving wireless device; determining that the device application does not exist on the receiving wireless device by the dispatcher application; and sending a notification to a user of the receiving wireless device of receipt of the message. Because the dispatcher application on the receiving wireless device sends this notification, the developer of the device application has an opportunity to sell the device application to the user, and the user has the opportunity to purchase the device application.
