OK, so I just posted the above comment, but since then, I think I figured something out. AT LEAST how to instantly turn of the ringing. The ringing did return, but at least it's a way to stop it temporarily, and I won't have to throw it against a wall immediately. SO, from your main screen, hit your "menu" button, go to "settings", then go to "applications", then go to "manage applications", then at the top of the screen click on "running". Find "dialer" and click on it, hit "force stop" and the ringing instantly stops. Like I said, it didn't last TOO long, but this is more info than I've seen anyone else post about stopping the ringing at all. So I hope this helps even a little bit.
