Thanks -- I was pretty sure that was the case. I have seen entire threads, including comments from Pete, that you can use SetCPU normally along with his scripts. Again, that's how I've been operating for months. Unfortunately, I have the box for "set on boot" checked already. Since my initial post, I rebooted and the phone seems to be back to normal. I'm going to monitor and see if it happens again, and if so, what I might've been doing to cause it.
