    Default How to Overclock iPhone 3G, 3GS, and 4!
    Hey guys, as far as i know, this works on iOS 4.0 - iOS 4.0.2. So, here are the instructions!

    1: SSH into your iPhone and goto /private/etc and backup the "fstab" file.
    2: Open up fstab in TextEdit (Mac) or Notepad.
    3: Add the following lines:
    su
    alpine (Unless you changed it to something else.)
    sysctl -w hw.cpufrequency_max=???000000 (Replace ??? with the MHz Ex: 600)
    sysctl -w hw.cpufrequency=???000000 (Same as above)
    sysctl -w hw.cpufrequency_min=???000000 (Replace ??? with the MHz you want when the iPhone is sleeping, etc..)

    Add those before:
    /dev/disk0s1 / hfs rw 0 1
    /dev/disk0s2 /private/var hfs rw 0 2

    So, in the end, it'll look like this:

    su
    alpine (Unless you changed it to something else.)
    sysctl -w hw.cpufrequency_max=???000000
    sysctl -w hw.cpufrequency=???000000
    sysctl -w hw.cpufrequency_min=???000000
    /dev/disk0s1 / hfs rw 0 1
    /dev/disk0s2 /private/var hfs rw 0 2


    4: Reboot your iPhone!

    (PS: If you try using a tool like Checkup, or something, itll say the same thing because it checks it using the model number and firmware model!)
