    Basically my iphone screwed up and crashed leaving me with only the apple Logo screen for over 4 hours.

    This was unlocked and jailbroken on 1.1.4

    In my panic and rush, I somehow upgraded my iphone to 2.0.2

    I have quickpwn'd my phone which has activated and jailbroken it.

    Only problem I have is that I'm now unable to use my O2 PAYG sim card.

    Is there a sim unlock for this firmware yet?

    Are there any step by step instructions for downgrading to 1.1.4?

    Please help.....

    I found this on yahoo answers

    Yes there is. I was in exactly the same situation as you were. Here are instructions I followed for Windows:

    1) Get QuickPwn RC3.

    2) Get the iPhone 2G Firmware 2.0.2 IPSW. Note the filename!

    3) Get bootloaders BL-39.bin and BL-46.bin.

    4) Place your iPhone in DFU mode and connect it to your PC with the USB cable.

    5) Extract the QuickPwnRC3.zip you downloaded in step 1 and run QuickPwnRC3.exe.

    6) Select iPhone 2G (the one on the left), click the next arrow.

    7) Click the browse button and specify the iPhone1,1_2.0.2_5C1_Restore.ipsw file you downloaded in step 2. Wait for it to load, then click the next arrow.

    8) Check the checkbox next to "Unlock phone". The rest of the options are up to you. Click the next arrow.

    9) Here's where you specify the BL-39.bin and BL-46.bin files you downloaded in step 3. Click the next arrow.

    10) Follow the instructions on the screen when prompted. This is where you'll need to press the home and power button in various combinations and durations. You can release the home button when the jailbreaking process starts. This should take less than 2 minutes.

    11) Wait for the iPhone to boot up. BootNeuter will automatically execute and select the correct bootloader. Don't touch the screen. You should see a message saying "Don't Interrupt!".

    12) After a minute or two, you will see a message saying that it will take up to 2 minutes to flash the baseband.

    13) Once the baseband has been flashed, the iPhone will return to the home screen. Your 2G iPhone should now be fully jailbroken and SIM unlocked!
    Would this unlock my sim to work with my iphone?

    Or does this just do what I already have done to my iphone?

    Never mind!

    I have managed to get it unlocked by using quickpwn on the 2.0.2 firmware and creating a custom firmware and restoring the iphone using this

    I then went into cydia and downloaded bootneuter

    Then opened bootneuter and neutered and unlocked my phone when I flashed it

    this managed to unlock my phone to the O2 Payg

    Not sure whether this is now unlocked for any network but it does the trick for me

    Hope this helps anyone else stuck with my problem
