how to i change the kernel i have? I rooted using unrevoked 3.3 and i want to overclock and do other things but i can't even figure out what a kernel is? is that unrevoked 3.3 or...something? how do i know if i can overclock on it? i searched overclock and kernel on the forums but i can't figure it out? i figured out ROMS well, kinda, but still have no idea what a kernel is?
