does this exist on the iphone? I'm one of the many looking at overclocking, and I found something about sysctl -w hw.cpufrequency=xxx, where xxx is the rate of the cpu. it seems you used to be able to do it, but now hw.cpufrequency is a read only file. Tuning with sysctl seems to say something about a loader.conf file that I have no clue where it is, but would allow the editing of this value.

any ideas?
