Oh, pulease people, if somebody says it's the OTA, don't expect a certificate with a Verizon Wireless seal on it to verify. We're all on our own here anyway. Even if it's not ---- run it or don't. Yeesh.
As to SetCPU and perflock and kernels, I have been running SetCPU just fine on ICS --- with profiles to underclock and no overclocking. I have virtually no heat issues that aren't related to something else (like letting the phone sit in the sun). You can't disable perflock on the Rezound --- not yet. Eventually we'll get kernel source and then the kernel magicians can do their tricks.
No, I haven't flashed this yet, but I fully intend to when I'm done the download and have backed things up here.
And I've also regained root with Amon Ra on ICS when I was pretty much screwing around with everything, but it doesn't really matter because a ROM can provide for root, e.g. Nils' 5.0 just out rebased on this RUU, not taking anything away from Con's brilliant work on the Rezound.
