    "When Pwnage 1.0 was released, it was indeed the ultimate hack for the iPhone/iPod Touch. Never before had the devices been under the user's control from the very bottom up. Prior, less sophisticated jailbreaks were still subject to the whims of the kernel, which couldn't be modified because the bootloader checked its signature and refused to boot if it was incorrect.

    Back in those days, the definition of "hack" above was still a feasible one, as the chain of trust ended at the kernel. Once you gained write access to the root filesystem, you could run arbitrary programs and make patches at will to many system components. Indeed, many such patches were needed, to make activation allow unapproved SIM cards, and to make Springboard display unauthorized apps.

    Fast forward back to the present, and you'll see the situation has changed. Solutions that using a ramdisk simply made a change or two to the filesystem now must contend with the mighty kernel's signature checking of all installed apps and libraries. Mounting the root filesystem and modifying /etc/fstab to make it writable is quite alright, but the moment you make patches for activation or anything else, the kernel will refuse to run the modified programs, unless you can somehow steal Apple's private signing key. Furthermore, such a jailbreak would be essentially useless because the system would refuse to run any of your custom software (such as Installer.app or Cydia), again because of the lack of signatures on it.

    Given the above situation, it becomes clear that if you want to use 2.0 for anything but screenshots, you either need to get ahold of Apple's signing key (start preparing your army now) or you need to patch the 2.0 kernel. Hard as we tried, we couldn't find much of an army, so we took the latter approach.

    We adapted our Pwnage technique to the 2.0 firmware, using a new unreleased exploit that we'd been keeping to ourselves, in the hope that Apple wouldn't patch it. This allows us to cut the signature checks out of the device bootloaders, allowing us to remove signature checking from the kernel, and enabling you to run all the custom software and patches you please.

    Please note other than my facetious army suggestions, patching the bootloaders is the _only_ way to get a functional jailbreak for 2.0. Under the aforementioned definition of "real hack", there is no such thing as a "real hack" for 2.0. I hope you agree with me by now that Pwnage, the exploit it uses, and its subsequent obliteration of the device's chain of trust, is a "real hack". "

    To those that say it's impossible to get your phone into DFU mode in windows: It's not the OS that puts your phone in DFU mode, it's you. You hold down the home button and the power button for ten seconds, then release the power button and continue holding the home button for ten more seconds, so a total of 20 seconds. This puts you into DFU mode.

    I was having difficulty getting Pwnage 2.0 to see my phone in DFU mode, it seemed like every time I got it to go into it, Pwnage told me I wasn't and I just kept trying until Pwnage told me I was all set to restore in iTunes.

    DFU in windows WITH iTunes 7.7 is not possible!
    If you use iTunes 7.5, it is working perfectly!

    So what from what i'm reading here. Windows users can pwn their iphones (3g even) just by doing that DFU mode process, then loading up normal itunes 7.7 and holding(or maybe pressing) shift before pressing restore and then browsing to a custom firmware image? If so, does that not mean winpwn is not needed? And thanks for the heads up. BTW, how do you know if your phone is in DFU mode?

    Edit: ok after making this post i see Calvin's post..if that's true..Can we[3g'ers w/ windows and others with windows] do the above process with 7.5 or 7.6 and pwn our IPhone?

    Edit2: I've another non-topic related question..but kinda..I think my iphone may be in DFU mode on accident..doesn't seem to want to turn on (was fully charged) but it wont do anything when i press the power button or the home button. Is that what DFU mode is? - I was actually planned on replacing my iphone today because of this..but if it's DFU then I guess I wouldn't have to.

    That's sounding good to me..was this all done on windows?

    BTW, how do you use this cydia? is it like an application on the iphone similar to installer which automatically lets you install certain applications from the net remotely? or do you have to do all the application installing through windows?

    So on windows, you need 2 computers:
    - First computer with iTunes 7.5 -> put in DFU mode
    - unplug iPhone and replug iPhone on the same computer to make sure you are in DFU mode -> iPhone screen should become Blank (white)

    - Second computer with iTunes 7.7 -> Shift-restore with any custom FW 2.0 made on a MAC (you can download it at a lot of places

    That's it!
