    Ok - so down to the steps that I did to get my Rogers and Fido phones working.


    I have done this now 4 times on my phone and also on friends & family phones with the same success consistently.

    There are some posts out there that mention that you do MIGHT NOT have to do ALL of these steps, but I've found that if you are not 100% sure of what was done BEFORE doing these steps, instead of trying to guess, just to do all the steps anyways, as it might only take an extra 5 to 10 minutes all of the steps that are considered “extra”.

    The perfect example of this would be that I've been playing with my phone since before Sept 12th and my buddy since Sept 9th and we must of upgraded / downgraded / DFU'ed / Restored DOZENS of times before we got it right with the help of forums & YouTube & the community. We've always been successful getting the firmware back down to / up to version 3.0, however we would always lose our carrier network connectivity after the Jailbreak / Downgrade process, until now.


    Here are my environment settings (from iPhone "Settings" > "About" screen):


    Code:
    Phone = iPhone 3G - 8 GB - Black
    Network = Rogers (or Fido)
    Line = Rogers (or Fido)
    Version = 3.0 (7A341)
    Carrier = Rogers 4.0
    Model = MB629C
    Modem Firmware = 05.11.07
    (Baseband)
    Here are the software apps that I used:


    iTunes version 8.1.1:
    (Newer version of iTunes like 8.2.x or 9.x will probably work as well, but I did not test these. Try your current version of iTunes, and if it does not work, do a full Uninstall iTunes via Windows "Add / Remove Program", and Re-Install iTunes using version linked below)
    Click Here for iTunes version 8.1.1 from MegaUpload

    iPhone 3.1 Firmware:
    Click Here for iPhone 3.1 Firmware from MegaUpload

    iPhone 3.0 Firmware:
    Click Here for iPhone 3.0 Firmware from MegaUpload

    QuickPwn App:
    Click Here for QuickPwn App from MediaFire

    Redsn0w App:
    Click Here for Redsn0w App from MegaUpload

    (Optional) DFU Force:
    Click Here for DFU Force App from MegaUpload



    *** NOTE: the iPhone Firmware Links above are ONLY for iPhone 3G and NOT iPhone 2G or iPhone 3Gs. If you are not using an iPhone 3G, please find the same version firmware built specifically for your phone.





    Step by Step:


    1. Connect your phone to your PC via USB and launch iTunes

    2. Get your phone into DFU mode (2 different ways)

    ----a. Instructional Article: How_To:_Enter_DFU_Restore_Mode

    ----b. Software App Tool: DFU Force

    3. iTunes will recognize that your iPhone is in recovery mode

    5. Browse to and select your iPhone 3.1 Firmware.

    6. Sit back and let Update run. This will take a few minute while you see Apple logo on your iPhone with Progress bar.

    7. After this restore, and the phone boots up, you SHOULD have Carrier Network Services. In our cases, it is either Rogers or Fido, but it should be whatever carrier your SIM card is set to.










    *** NOTE: At this point, if you are still not connected to your respective Carrier Network, then I would suggest you do not continue further with these steps. You could of course repeat Steps 1 to 7 again if you have any doubts, but if you still are not connecting, then these steps no longer apply to you and you should start doing research for an alternative method.


    8. Close iTunes.

    9. Open your Windows "hosts" file with NOTEPAD. Typical location:


    Code:
    C:WindowsSystem32driversetchostsHere's an example of what the "hosts" file looks like:







    10. Add the following line to the END of your "hosts" file:


    Code:
    74.208.105.171 gs.apple.com11. Save & Close your "hosts" file.

    12. Re-Launch your iTunes.

    13. Do another RESTORE as you did in steps 2 to 6 > However this type select iPhone Firmware version 3.0

    14. At the end of the Update (similar to process in Step 6), you will get an error in iTunes - DON'T WORRY, THIS IS SUPPOSED TO HAPPEN:


    Code:
    The iPhone "iPhone" could not be restored. An unknown error occurred (1015).




    15. Clear the error in iTunes by clicking "OK". Your phone should now be in RECOVERY mode (and not DFU mode). See image below. If you are not sure what mode your iPhone is in, just put it back into DFU mode as explained in step 2.






    16. You now need to REPEAT for a SECOND time the RESTORE process as explained in Step 13, RE-Selecting the iPhone Firmware version 3.0. You will be essentially repeating steps 4 to 6 AGAIN, except for the firmware version.

    17. You will ONCE AGAIN see the SAME error as you did in Step 14. ONCE MORE, THIS IS NORMAL AND YOU SHOULDN'T WORRY.

    18. Close iTunes.



    *** NOTE: Read Steps 19 to 23 in advance before continuing.



    19. Launch QuickPwn, BUT DO NOT CLICK ON ANYTHING ELSE. (Read all of Step 20 before continuing)

    20. You should see a standard Windows window (and not the QuickPwn app) pop up and instruct you to "...hold home button \ sleep wake button for 15 secs etc..." >>> Go ahead and do this, AS SOON as you see the Apple Logo appear on your iPhone, go ahead and click "OK" button on the dialog window. DO NOT CLICK "OK" UNTIL YOU SEE THE APPLE LOGO.

    21. After you click on "OK" in the MS Windows message box, pay attention to your iPhone. You should see a progress bar VERY BREIFLY as shown in Step 6.

    22. Once complete, you should arrive at a screen similar to the one below (message in blue box might be different):



    This image has been resized. Click this bar to view the full image. The original image is sized 500x443 and weights 45KB.




    23. Once your iPhone gets to your "Lock" screen, you can exit QuickPwn Completely.

    24. Open up itunes and allow you iphone to activate through itunes, you will be asked to download carrier setting click ok. your phone sould reboot in to normal oson 3.0 unjail broke with carrier settings.
    25. put phone into recovery and jail break with redsn0w 0.8 sould go through with no problems



    26. There are several very good illustrated guides out there already:

    ----Guide 1: Jailbreak iPhone 3.0.1 Firmware with redsn0w

    ----Guide 2: iPhoneModding Guide to redsn0w
    ----Guide 3: redsn0w Jailbreak Guide for iPhone using Windows


    27. It is interesting to NOTE that on about 50% of the phones that we did, redsn0w would FREEZE or LOCK UP between the "Installing Bundles" and "Syncing Filesystems". THIS IS OK. Just run redsn0w a second time (Steps 25 to 26) and you will be fine.
