    This does not work.
    The swap file is not created by dynamic_pager..
    If I manually create swapfiile0 with `touch`, it is not modified by dynamic_pager..
    The only reason why the screenshot in this tutorial shows as much memory as it does is because the iPod Touch 4G has 256MB of ram.

    worst idea ever. no offence (not to flame/ hate whatever) but:
    1. you have Mb of RAM do you really need to burn your Flash memory for this????
    2. RAM only ever lowers the speed of your device when you have little of it. around 20-30Mb free at the most will be the free memory that will slowing you down apart from that im quite sure you should be thinking about the processor....
    think about this because this is a wasteful burn of FLASH memory .

    Clearly you installed it wrong.

    The flash memory isn't going to die a year from now because of this. It still has a long life span, just not as long as not using it at all. If someone installed this on, let's say their iPod Touch 1G the day it was jailbroken, it would still be working fine today (the flash, that is. Not sure about how the battery would be since they naturally wear out). There are plenty of other things that can kill your device's flash faster, don't know why this is so looked down upon. It's up for the user to weigh the pros and the cons.

    Dude, you can't estimate that. I've seen iPhones die after two weeks. I've seen some die after a month. It's still not worth it. The iPod has a sufficient amount of RAM. And the original one does work, just used it one my iPod. Don't go around making up lies.

    Also, if someone says it didn't work, HELP THEM, don't accuse them of doing it wrong! I've seen that too many times, "it worked for me, so you did something wrong!" not always true.

    Also, you have no proof that the iPod 1g would still be fine today with this tweak. It most likely would have died. My 2G began to die after 6 months. I have since had it replaced with apple, headphone jack problems. You have no proof of this.

    I 100% agree!

    This burns through flash memory on a computer!
    so I would bet it would on the iPod touch to! :p

    @Matt, you said it was up to the user to weigh the pros and cons, yet you have stated only pros... There are more cons than just the flash too... If you tell users to weight the pros and cons, and don't give cons, how does this allow them to make an educated decision. I could care less whether or not people use this, it's up to them. But I don't like it when people use it without knowing the consequences. They are essentially frying the iPod without knowing it when they do that. List some cons in the OP (ALL of them, not just one or two). Then allow them to make the decision. Also highlight them in RED (Helps distinguish; highlight the pros in green).

    Let me explain some cons (There may be more):

    -Lagging: Flash memory wasn't made to do this. It doesn't have as fast of read/writes than RAM. Therefore, every so often you will get a lag from this. Sometimes it will become unbearable (I speak from experience). Most people think this is a stability issue, the fact is that it is an issue with the Flash memory's speed.

    -Less free User Memory: This tweak uses Flash memory. On an iPod with 8GB, about 6 are free. Using 512MB of RAM (and more if needed) is about 8-10% of the user's free memory. We also know that when this dips low, your device also become unusable.

    -KILLS the FLASH memory (This is hardware, not fixable on your own): The flash memory has a number of read/writes it can preform. When this number runs out, it's done with. Your iPod will not boot up. Apple won't fix it if they find out. The timing on when this happens is unknown. "Professionals" have estimated 2 years on a flash drive with Windows 7 (But the computer already has 4GB of RAM and rarely needs to use this), but on the iPod it is going to be used more. Therefore, it will die within 2 years. I have heard stories about iPhone 3Gs dying after 2 weeks. Mine survived 6 months before it showed signs of wear and tear. I don't abuse the RAM.

    Both Apple's implementation and this one, along with iMemoryEnhancer will do the same thing to your iPod. It'll eventually kill it. This is why it's not a feature of the OS, but can be enabled. The VM on Macs was originally for use on hard drives (Far larger read/write cycles than flash). Since it was in OS X, and the iPhone OS is based off of it, it found it's way into the iOS, but was never activated until around 3.0 (Maybe 2.x).
