    Is it possible now? I tried before through a few methods (most CLI) but processor stayed at 533 MHz

    Also, is there an app that uses the flash memory as RAM more smoothly than iPhoneVM? That thing freezes me regularly to (presumably) swap files.

    I tried this once! Worked well. Its only virtual memory.

    For the virtual memory try the .plist method.

    Virtual Memory is not an overclock. There is no way to software overclock a 3G's processor.

    Virtual Memory will allow you to run many apps at once, but at the expense of slowing things down while memory is paged to and from flash storage. This makes for a fairly unresponsive experience at times. There has been discussion regarding whether this wears down the flash memory especially quickly, and the general consensus was that it would take years and you'd likely have a new model by such time.

    Also, iPhoneVM has been reported to send iOS4 into an endless boot loop, so only try it on version 3.

    There has to be some way to at least remove the processor limit apple but in place. Apple upped the speed once via software update, so there has to be a way for us to do it.

    Seriously, I don't care if this phone blows up, I have others. I want to remove apples limit or at least up it a little. I maxed out the cpu on my mytouch which is pretty much the same as the iPhone and iPhone 3G and the battery life didn't drain as fast as I thought it would, nor did it get much hotter. I don't think the effects would be much different on the iphone.

    Planetbeing knows how to overclock/underclock the iphone. I asked him in irc once and he said it's not ready yet. The processor speed is determined in the kernel (in the 1.1.1 days, you could change it through terminal).

    No, removing that just stops the processor from slowing down in idle, screen locked. It will just kill your battery.

    You can find patched kernels on xda. Install the kernel and use SetCPU to adjust the speed.
