For those that haven't noticed. SetCPU does work on the Rezound with root. The kernel apparently supports under clocking (not overclocking at the moment, this requires a custom kernel). I've tested the cpu and confirmed the clock speeds with System Panel. I've been pretty stable at 918mhz which should show some decent battery improvement with little to no difference in general performance. I haven't tested with games if it shows signs of lag. Others may want to play around while we wait for full root and custom kernels.
