Just rooted yesterday with smoked glass. Couple questions with speed. As I was setting it up, I adjusted the speed to 250-1000mhz. So is the setcpu app needed? Would they offset each other? Seems from what I read, setcpu can adjust the phones speed whenever you want. Is that the only advantage? And if I decided not to use setcpu, when would my phone perform at its highest set speed on this smoked glass? Thanks.
