My warranty replacement came 8/29 with ICS and so far is working flawlessly. Biggest irritation is resetting up the phone but my backup pro installed my 174 apps flawlessly with the unavoidable irritation of having to setup a lot of apps individually after starting them up.
For the earlier poster, the reason I needed a warranty replacement was that the four capacative buttons suddenly stopped working on my original rezound. The phone still worked perfectly as long as you control whatever you were trying to do from the touch screen, but once you got to a point where you needed the back button (for example closing a picture) your only way out was to reboot the phone.
