    I was reading around in the "New Posts" and I came across a couple threads where people wanted to overclock their iPod Touch's processor.

    There was information on how to view your processor speed, and the command that would allow you to set the speed (if it were allowed by the kernel.)

    More to the point, that command was 'sysctl -w hw.cpufrequency=***CLOCKSPEEDHERE***', which was denied write access.

    I was messing around with the command and found that (in the description in terminal) 'sysctl -a' would show information about the device like:

    To view a specific variable you would type 'sysctl hw.cpufrequency' or other variables:

    Furthermore, you can narrow down the information given by only typing for example, 'sysctl hw', it would only give you information about the 'hw', or hardware:

    None of these variables are actually writable, but I researched a bit, and i think I have found that these are set on the kernel build. My thoughts are to enable/disable or changed the value, we'd need to compile a new kernel.

    As stated above, can anyone confirm this?

    Any and all comments are welcome.
