Ninjamorph does work to change icons, but it doesn't work as good as it used to in Froyo. I changed my Vibrate icon yesterday shortly after i flashed 596. The only problem that I had was that when I tried to finish the project, my phone gave me some sort of an error that wanted me to force close ninjamorph that kept reappearing. The only way out was a battery pull. When it booted back up, all was good including my changed icon. Just sayin, it does work, but be prepared for the worst....
