whiteout is right.... hashcode's ICS (both CM9 and AOKP) work almost flawlessly for me. I have used both, and they both have everything working, including front facing camera now! with only little bugs here and there that will be worked out shortly.
keep in mind, this phone has only been out for a month, and there are no stock recovery files out there for us if we really eff somthing up.
dont know about you, but i am thrilled with the development so far and LOVING my ICS experience on the droid4.
