    Changing the file com.apple.SystemPowerProfileDefaults.plist
    (Located in: /System/Library/SystemConfiguration/PowerManagement.bundle/)

    All of these should be set to this (there are a few throughout the .plist):

    <key>Reduce Processor Speed</key>
    <integer>0</integer>

    Is it necessary to edit this file?

    Well...
    Just changing "com.apple.SystemPowerProfileDefault.plist" canīt be the best alternative to overclock your device, or is it?
    I mean, just hiding that .plist from your device can cause lot side effects like overheating and the loss of control (?).
    Though iīd like to know if this works with every firmware.

    Yesterday iīve started to deal with this subject and tried to use "thameythidd"s suggested way to overclock my ipod touch gen2(mc).
    But I didnīt find the cited command lines in the "SystemPowerProfileDefaults.plist".

    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

    Reboot device after replacing original files on the device with the modified ones.
    Any ideas where i can find it on my device?

    You didn't find them because the lines are not there until you add them, just make the file look as I have shown. As for if it is necessary to edit the com.apple.SystemPowerProfileDefaults.plist (Located in: /System/Library/SystemConfiguration/PowerManagement.bundle/) I'm not sure but that is the method that I have used on a 2g and a 3g that has worked on both. My guess would be yes because all of the reduce processor speed commands.

    Yeah i already have thought that iīll have to add the lines but i didnīt want to mess around that much with my device. (<---I do not know anything about that kind of stuff but iīd like to learn a lot about it)

    I think i will try to add the lines in the evening, looking for any improvements.
    By the way...i guess you wouldnīt recommend overclocking too?!?

    And can u explain how you did know where to insert these lines?

    Maybe U can try this~ See whether it works~

    his virtual memory can be used by your device to perform normal functions while you play games and listen to music and have a movie downloading in the background with extra memory to spare. So lets get started!

    1. Make sure you are jailbroken. (How do I do that?) And that you are on or at an above firmware of 3.0. (How do I check?)

    2. Open Cydia then, in the bottom right corner tap on the Manage tab.



    3. Tap on Sources then in the top right corner tap on Edit, then Add.

    4. Type in http://repo.beyouriphone.com and press Add Source.



    5. Once it's done, in the bottom right corner, tap on the Search tab.

    6. Type in iPhoneVM 2 (OS 3.X) and tap on it.

    7. Install iPhoneVM 2 (OS 3.X) to your device.



    There you have it, once you restart your device, you will have much more RAM to use for more functions.
