    i know there are many threads on this, but I'm just exploring... is it possible to remove the root password? not change it, but remove. I have heard people talk about editing the "fstab" file in /private/etc, but there is a flaw in it.

    entering:
    su
    alpine

    will not work because "alpine" is not a command. if the root password were not there, then it would be possible to overclock the iphone/ipod touch... i think T_T. After I'm done, I'll resecure my ipod with a password though.

    So are you trying to edit the file (fstab) with terminal?

    now that i think of it, overclocking is impossible. "hw.cpufrequency" is a read-only file and i can't find it... unless someone finds it first, I have no hope

    What? I'm a tad confused.

    'su' simply lets you execute commands as root, and 'alpine' is the default root password. Neither of those influence CPU frequency.

    i know, i then type some other stuff afterwards in order to change the file, im just saying how can i automatically become superuser upon boot... after typing
    su
    alpine

    i then enter

    sysctl -w hw.cpufrequency_max=550000000
    sysctl -w hw.cpufrequency=550000000
    sysctl -w hw.cpufrequency_min=450000000

    or something like htat

    you know in the boot process you are already a root user. hw.cpufrequency I assume is on another partition...

    That method of overclocking already works, but only on the iPod toucb 1G, iPhone 2G, and iPhone 3G due to their old ARMv6 architecture.

    And I have GeekBench benchmarks to prove it.

    However on iPod touch 2nd gen and above (which use ARMv7), this does not work, due to newer bootroms and a different architecture.
