Blackberry Message Receive App Framework

Basically I need the following framework: User installs an application on a BlackBerry device which listens to the SMS message port on the device. If an SMS message comes in with the text: X1T2E3, the application does the following: - Displays a dialog box saying "Blue horseshoe loves BlueStar Airlines" with "OK" as the only user action. - The SMS is never shown in the INBOX. This is for BlackBerry devices only. This is a framework for something else so as long as I can SMS the above from one phone to the BlackBerry with the application installed, it is a complete project. To turn this on/off, there should be a simple settings page which can be found on the options menu of the blackberry.
