I'm still going to wait for the ifixit guys to tear this baby down before I'm ready to concede it's the 4430 and not the 4460 in the RAZR. Either way, I don't think it's a deal breaker, but it still makes little sense to me why they would overclock a phone that is heralded for its battery life when it's cousin would fill the same space (and presumably, similar cost) while being underclocked, thus saving battery consumption. The "improved 4430" is plausible, but I agree that documentation would make me a believer. YMMV,
