    How To Trick iTunes into thinking that you have 4.0.2 or 3.2.2​


    As you all will have noticed 4.0.2 (and 3.2.2 for iPad) is out, which you should also know kills the Jailbreakme.com jailbreak and unlock on MC Devices.
    You may have seen this:

    That "Download and Install" button looks awfully (un)friendly and can be easy to click.

    Before we start.
    Disclaimer:
    I take no responsibility for any damage or loss (bricking .etc) of your iDevice (iPad's, iPhone's, iPod Touches). Any damage occuring is your own fault.

    This tutorial explains how to spoof your firmware version, with the main aim of tricking iTunes and Apple into thinking that you have the latest firmware, so that you don't get update notices.

    First you will need either an SSH client or iFile installed.
    I used on a 3G iPod Touch 32GB with iFile.

    SSH or navigate to: /System/Library/CoreServices

    Locate the file called "SystemVersion.plist". I also strongly suggest making a copy incase you corrupt it. If on SSH drag this file to your desktop and open it with a text editor, or if using iFile click and select "Property List Viewer". You should see something like this:

    We are going to change two things in this.
    1. The "ProductBuildVersion"
    2. The "ProductVersion" (iOS version/number)

    Because I am on a 3G touch my present build is '8A293'
    Change the build to:
    iPhone/iPod Touch: 8A400
    iPad: 7B500

    Next change 4.0 (or 4.0.1 or 3.2.1) to:
    iPhone/iPod Touch: 4.0.2
    iPad: 3.2.2

    If past iOS 4.0.2 click here to find the latest build for you device and firmware.

    Your SystemVersion.plist should now look like this:

    Hit save.

    If you are using SSH drag "SystemVersion.plist" back to it's original location and Reboot your device, iTunes will now recognise your device as having the latest firmware.

    Just for proof here is a screen shot of my device showing 4.0.2 on an MC with cydia installed:

    I hope that this has been helpfull,

    Why would you need to trick iTunes when you can just press Cancel?

    Or just download. Either one.

    My way you don't have the there is a new update availiable notice when you view your device.

    I prefer mine to show the latest firmware, others might to, this is how they can do it.

    I did this already, yet to no avail. It looks cool in my Settings > General > About, but iTunes still thinks it's 4.0.1.

    Or you can just ignore it! Just leave it alone, it causes problems with the PDF patch, so its best to put that in the OP and leave it.

    I just select do not ask me again and click cancel, when i connect my itouch to pc i never get asked to update, so i don’t have any risk of updating unless i manually go and look for the update which i wont.

    Problem solved
