I got the same story, after update the firmware, i got carrier null null at the network..my sim cannot be recognized by the iphone, btw i got 2.2.1 firmware and 6.02 bootloader and 2.30 base band.. iphone 3g (as you’ve said this cannot be unlock)
for the users have the same problem (carrier null null) you dont have to use rebelsim,turbo sim etc to use your iphone after this..
here’s how i did it..
you need this requirements:
itunes 8.1
firmware you want to upload to your iphone (2.2.1 / 2.2)
quickpwn 2.2.5
Follow this method…
- Start iTunes 8.1 for WINDOWS ONLY! i have no MAC so i dont know if this is possible with MAC users..
- Connect iPhone 3G via USB cable
- Put the iphone into DFU mode (hold home + power for 10 seconds, continue holding home for 10 seconds)
- At the restore screen in itunes “Shift-Click” Restore button, choose the firmware you want to install 2.2 or 2.2.1
- finish the entire processes, “Error 1013″, should pop-up, cancel it and immediately close itunes before it tries to connect to the itunes store!
Note: if you got error message like 1011, 1013, 1015, just ignore them, its actually the firmware 2.2.1/2.2 is already successfully installed.
But if you encountered with error message like 1601, 1602, 1600 or anything else then try putting the iPhone into DFU mode again and try again. these means you did not achieved the correct method on how to go to DFU mode
- Open QuickPwn 2.2.5. it will say “must hold power and home for 15 SECS, then press power for 2 seconds” but hold the power button+home for 10 SECS ONLY then release the hone and power button then hold the power button for 2 second..
- Click OK and exit out of QuickPwn!(do not go thru quickpwn - no need!)
- Your iphone will show a black emergency screen with itunes logo on it. (after you press the hold botton (2 Sec)
- open itunes or wait for itself to open automatically.iTunes will take some time to recognize the device and connect to the apple store to unlock your iphone, “it will say your iphone has been unlocked congratulations..
- Your iphone will say “slide to unlock” do it, iTunes then prompts if you want to restore from a backup or it up as a new iPhone. Select new.
- Now you can use quickpwn if you wish to jailbreak it!
Just in case still no network after these steps: (waiting for activation after 10 mins minimum)
1. Follow all steps detailed in this guide.
2. Connect iPhone to iTunes.
3. Set up as new iPhone.
4. Wait for iPhone to say activating.
5. Slide iPhone to unlock.
6. Settings > General > Reset > Reset network settings.
7. Your iPhone will turn off and reboot.
8. You should have a message saying “iPhone is activated”.
If still not, turn your iphone off, remove your sim and insert it again…
then open… then repeat 2-8 steps above..
then you should activated it..
If again still not activated…
Its time to jailbreak again the iphone…
- Open Quickpwn 2.2.5
- run it - choose your firmware (2.2/2.2.1)
- jailbreak it…
After Jailbreak - open cydia look for yellowsn0w software (its 0 zero not o letter for snow) then look for carrier bundle software..
install it..
turn your iphone off, remove your sim and insert it again…
then open… then repeat 2-8 steps above..
then it should have the network signal by that time…
Hope guys this will help..
i did this all and my iphone now already have network again and using it without rebel to turbosim..

Let me try to sum up "twotallanti" post - just for my understanding:

- Start iTunes 8.1 for WINDOWS ONLY!
- Connect iPhone 3G via USB cable
- Put the iphone into DFU mode
- At the restore screen in itunes “Shift-Click” Restore button, choose the firmware you want to install 2.2 or 2.2.1
- finish the entire processes, “Error 1013″, should pop-up, cancel it and immediately close itunes before it tries to connect to the itunes store!
- Open QuickPwn 2.2.5. it will say “must hold power and home for 15 SECS, then press power for 2 seconds” but hold the power button+home for 10 SECS ONLY then release the home and power button then hold the power button for 2 second..
- Click OK and exit out of QuickPwn!(do not go thru quickpwn - no need!)
- Your iphone will show a black emergency screen with itunes logo on it. (after you press the hold (you mean home?) botton (2 Sec)
- open itunes. iTunes will take some time to recognize the device and connect to the apple store to unlock your iphone, “it will say your iphone has been unlocked congratulations..
- Your iphone will say “slide to unlock” do it, iTunes then prompts if you want to restore from a backup or it up as a new iPhone. Select new.

Now the iPhone should be unlocked e.g. using BB2.30.03 and BL5.9??? Can anyone confirm if this really works?

Cheers,
Tim
