    TO SAVE YOUR READING TIME: THIS DOESN'T WORK. DON'T BOTHER

    At the risk of beating the dead horse yet again, I'm going to provide a guide (very poorly written but nevertheless), to overclocking the 3G.

    I should note, this has NOT been confirmed, the folks over at a shady forum (sinfulblah blah) have been up in arms arguing over whether this works or not.

    For the record, I don't know whether it works or not, but I don't see it harming your system, so if you think it helps, then good on you, otherwise, you can ignore this or you can flame me, I don't care.

    Anyhow, this is what I've learnt.

    The idea is to modify the fstab file which is an essential boot up file. In other words if you do implement this BACK UP YOUR PHONE FOR YOU MIGHT NEED TO RESTORE.

    Anyways, I did it via iFile, you can simply use SSH and modify the file that way. Or use cyberduck to SSH into phone and pull off the fstab file, edit then reupload.

    So, navigate into /Private/etc and there should be a file called fstab.

    If you are using iFile, you can edit it on your phone, otherwise find a way of editing the file.

    When you open the file it should look like this:

    Now the next step is to edit the fstab file:
    The code in red is what you add to fstab, note that it PRECEDES the other lines of code.

    Please note: DO NOT MUCK AROUND WITH THE ORIGINAL lines! Leave them there! Or you will need to restore.

    Save the file, reupload it if you did it via Cyberduck, etc.

    And reboot, and away you go. Note this will make boot up slower, you just made fstab about 3 times its original size.

    I am not sure if this is real or not, but I have had some minor positive speed increase, which may be placebo, I don't know.

    In any case, good luck, and remember BACK UP!

    In short, nope.

    I understand it to be a file which tells something to mount some files.

    But there was a suggestion that it could be used to execute code.

    I could of course be wrong.

    Like I said, I didn't come up with this idea.

    Well, perhaps if you have no idea what a file does you should refrain from making posts about hacking it.

    fstab stands for file systems table, and it is a file which contains information about your system's partitions (hard disks, removable memory, etc.). It is used by the OS when mounting these partitions, most notably using the 'mount' command. It does not "run code," and it has absolutely nothing to do with CPU clock speed.

    I have to say, this is the most ridiculous think I've seen on this board in a long time. Someone on whatever forum you found this on must be having a good laugh.

    Ahh well, now I know. Proper adjustments made to OP, and we're good to go.
