Have you ever considered making your device go faster than what the manufactures tell you it does? Well you can with the HTC HD2 and LeoCPU Speed. The application is a very complicated but simple to use tweak that allows you to change the clock speed of your HTC device.
I have used this before, and wow, it actually works, and it does it quickly. When I first started, I tried to see how low can it go. It does not work very low on the HTC HD2, but it does do high.
I was able to over clock my HTC HD2 at the sounds to the highest 1228Mhz processor speed. That means my device almost hit the new processor speeds, but here is the problem. I went to the highest and it failed, and everything turned off. That means you can feel the power the HD2 has, and to conserve power, you simple turn it back or to the lower number.
This application is pretty cool, and it allows you to do a lot.
