This should be old hat by now -- an ICS ROM has leaked out for the HTC Rezound. Just like the last leak, and the one before that, and the one before that, you need to either be S-Off or completely stock to load it, and this go 'round it brings new radios, and (you won't like this part) takes away the hidden dialer menu. That means if you've been using the Rezound on T-Mobile or AT&T, you'll want to stay far away from this leak, and likely the official update when it comes around. If you're rockin' the Rezound and wanna give it a look, hit the source links.
