Please beta test our iPhone medical app (improved based on HN feedback)

I just played with it for a few minutes so far, and my medical background consists of 7 seasons of House on Fox, so take this feedback with that in mind.

Some fit/finish things:

1) The Main Menu lets you scroll, but doesn't do the "iOS bounce" when you get to the top or bottom. If you're not sure of the effect I am talking about, you already use it on the "Discuss" screen.

2) When you tap "Finish" and get the "Are you really finished" dialog, the "No, not yet!" button is black on a black background. Perhaps you can go with a red button with white text, or something else that conveys "Cancel" and stands out against the background.

3) When you are on the "Manage" screen, the "on/off" buttons would be better as "Yes/No" buttons. "Urgent Surgey ON" isn't as nice as "Urgent Surgery YES".

4) The app is totally silent, which isn't bad but it feels kind of "eerie" to me. Maybe some background music of some kind, and key click sounds as you toggle things and change screens? Perhaps a little jingle at the end that changes based on how well you did? Like a "patient flat line" sound if you do badly, or a "da dah trumpet" if you ace it?

I hadn't seen the earlier version, but I just got the latest beta. It would be nice to have a more detailed grade for each case, so that I could learn in better detail about the investigation & management choices I made vs what the ideal choices were.
