That's odd, when I installed my OTA Froyo I checked my alarm before I went to bed that night and was glad I did. The settings were still there but no sound selected. So I selected my favorite that I had always used and it has been working fine since. I use the stock alarm that came in the Droid. Several of my sounds were changed to other sounds in my list. I now have them all back to what I had. But I didn't lose my alarm app.
