    here, download 1.1.1 firmware here

    1.1.1 Firmware

    Step 1: Downgrade to 1.1.1 (if required)
    *** NOTE: This guide does not guarantee it will work 100%. Also errors 1015 is expected at
    the end of the process. Continue reading to understand. ***

    1. Download the 1.1.1 ipsw firmware file from Apple. If the downloaded file has the extension
    ".zip", please remove it and modify it to end up with a filename ending in _Restore.ipsw

    2. Reboot your iPhone holding the top (power) and home buttons BUT release the top button 10
    seconds into it (right after the screen goes dark) and continue to hold the home button until
    iTunes detects the phone in recovery mode. The iPhone screen will appear to be off, but start
    iTunes if not started yet .

    3. Restore your iPhone by pressing and holding the ‘Shift’ key on windows or ‘option’ key on Mac,
    then click ‘restore’ to select the 1.1.1 firmware file you downloaded earlier. The restore should
    go through and errors at the end with error 1015. However you will notice that the iphone is in
    DFU mode with the connect to itunes screen from 1.1.1.

    4. In order to kick the phone out of that mode, start TouchFree by double-clicking "windows.bat"
    on Windows or "jailbreak.jar" in OS X, then click the "Boot from Recovery" button.

    Then i do this Jailbreak The downgraded iPhone,

    Step 2a: Jailbreak 1.1.1 on Unactivated iPhone
    *** NOTE: If your phone has been activated through iTunes, you can proceed to step 2b. ***

    1. enter *#307# press call, now use the back button on the top of your screen to remove *#307# ,
    now enter 0 , press call, press answer, press hold, press decline. And you get to the contact
    list. And thereafter every time you push the homebutton you just slide the "emergency call"
    slide, then enter 0 , press call, press hold, press decline.

    2. Push contacts, end call and you get called again, this time hit decline and you access one of
    menus with favorites, you can edit contacts, do a test ride on keyboard, take photos etc.

    3. Now edit a new contact and type in "prefs://11" as web-address and "" as
    an additional URL.

    4. When you tap "prefs://11" you can now select your favorite WiFi gateway.

    5. Now press the home button and move the slider to the dial-pad.

    6. Now you can go back to the contact list by Dialing 0, push call, then answer, then contacts,
    then hit the "" web address you typed in.

    7. Scroll down to the bottom, click "Install AppSnapp". Safari will exit and you'll return to your
    springboard. Wait for the phone to reboot. You are now jailbroken. and are able to use

    Then do this to prepare for update?

    Step 3: Prepare your 1.1.1 device for the Update

    1. Launch

    2. Scroll down to Tweaks (1.1.1)

    3. Select OktoPrep

    4. Click Install

    Then Do this to update to 1.1.2

    Step 4: Update to 1.1.2

    1. Connect your device to your computer

    2. Launch iTunes

    3. Choose your device

    4. Click Update
    - If update still shows 1.1.1 as being the newest version, you may download the 1.1.2 from an
    Apple download server and shift-click (PC) or option-click (Mac) on "Check for update" and
    select the update you downloaded.

    - DO NOT CLICK OR SHIFT-CLICK RESTORE: That will wipe the changes OktoPrep made.

    5. Wait forever for your device to update

    Hopefully this helps

    assuming that you have a iPhone that came with 1.1.2 out of the box, you can not unlock the iPhone, you cant even unlock the iPhone (if its 1.1.2), when you downgrade to 1.1.1, because of the baseband thingy,(i think thats what its called lol) is what you cant unlock.

    The procedure i explained was to Jailbreak the iPhone, and by doing this you can only use O2 simcard in the iPhone, wether it be a PAYG or a Contract Simcard. No other network simcard will work.

    Hope this helps
