I agree. Under clocking your cpu is worthless. All new mobile processors do a good job of this themselves. Now if you want to over clock these are nice programs. But keep in mind that your device and cpu were designed to run at the default clock speed. If you change that of course things are going to mess up.
I used pocket hack master since version 1.0 and primarily for under clocking. After realizing that it saved no battery life I got rid of it. I helped beta testing over clock settings on one of my pocket pcs with a new processor once. I never rebooted soo much.
So don't bash these programs for making your device unstabe... that is what they are designed to do. :lol:
they are definitely for power users who really want to mess with their device on a hardware level.
