Attached is a rough outline of what the application should do -- retrieve XML data feed from remote data source, communicate with Web service, use "Alert" functionality to deliver data to the device without the user taking action. Not sure if Facebook functionality is available for the Blackberry - if so, then the user should be able to login to the application with their Facebook account (<[url removed, login to view]>) as well as through a traditional login system.
An example of the XML feed for the application can be found at: <[url removed, login to view],[url removed, login to view]>
Let me know if you have questions.
