From your question it looks like you haven't heard about network transports. If this is the case, then it's a miracle your app worked OK on the first device! :)
Network transports is a BB specific concept. Check Connecting your BlackBerry - http and socket connections to the world. Basically you end up with a url that is appended with a specific string that tells to the BB internals what network transport to use.
