Application works fine in Preview but doesn't play on iPhone?

Question

I finally decided to purchase a Developer license to start testing performance of my game on my actual iPhone. My game works perfectly on my computer, however I published to my iPhone and when it loads, it shows the graphics of the game but it is as if the game never starts. It is just frozen on the first frame of the game.
I've tried doing a remote debugging session but it won't connect for some reason. I'm on the same wifi network, I've published from Flash using the Quick for Debugging option. When I load the game, it freezes on the first frame and doesn't ask for the IP of my computer (which is supposed to happen on debugging right?)
What should I try from here?

Answer 1

I got debugging working: I'm getting an error:
Error #2044: Unhandled IOErrorEvent:. text=Error #2032: Stream Error.
It corresponds with the first line of these three lines:
loop = new Sound();
loop.load(new URLRequest("hitit120.mp3"));
loop.addEventListener(Event.COMPLETE, startMusic);
I've included the mp3 file in the iphone included files publishing setting... Although what is weird is the stream error happens on the first line, before I even try to load the mp3..
