SetCPU is a CPU speed tweaking application for Android. More specifically, it allows control of certain aspects of the Linux cpufreq driver, allowing for overclocking, underclocking, or tweaking speeds and settings on many Android devices. It will work with most if not all rooted Android 1.5/1.6/2.0/2.1/2.2/2.3/3.0/3.1 builds on most devices.

The program is free here for XDA members. It costs 1.99 on the Android Market and available for purchase on the Amazon Appstore for users in the US.
