First off I did the root from Root from MotoCach's "root regardless of os" with rsdlite and sprecovery. my current android version is 2.2.1 ( I have no idea which version this is) and the current kernel is 220.127.116.11-g68eeef5... Which kernels am I supposed to be using is my question. I've install titanium back up(free) and setcpu. Anything else I should take care of before changing the kernel?
