I got my froyo upgrade this morning. Other than disabling my unauthorized swype installation, there is only one problem. My Dinc now makes a loud scream sound when the screen blanks/locks. This is not the selected notification sound. In fact, I have no idea where this sound came from, since it doesn't show up on the list. I have screen lock sounds unchecked, but it doesn't seem to make a difference whether this is checked or not. Any suggestions? Needless to say, this is a bit of a hassle in meetings.
