guys!
accidentally i upgraded my iphone 3g to 2.2.1 throw itunes, as you might know it is almost impossible to unlock. not because of the firmware, but because of the base band (modem firmware).
i tried everything and it was almost impossible!
but it’s done! and it is unlocked.
all you have to do is…..
get the firmware 2.2 (official)
downgrade using itunes (pressing shift+restore on sumary board)
if your baseband is 2.30 it will give you an error lile “1013″, but do´n’t worry the firmware is installed.
then it will say that iphone is on “dfu” (service mode) while this run the QuickPwn and jailbraik the iphone
install a 2.2.1 custom firmware
install from cydia the program fuzzyband to downgrade the base band to 2.28
install yellowsn0
and thats it, it is done and working

@ dr. virk – thanx mehn. so u mean with gevey turbo sim there’s no kind of unlocking done on the phone actually, or is there some kind of installation that’s required for the turbo sim to be active? because i just jail broke mine, n i think any kind af installation/unlocking or wateva that might have been done before will be undone, right?

nah man. dont worry. With Gevey’s Turbo chip its not unlocked. Its just a method to bypass the lock. And I have read many a times that it works perfectly. If it stopped working for u, check the method of sim insertion. So feel free. u wont be facing any risks except that i have read somewhere some fool tried it wrongly and put the gevey sim without the iphone sim holder and while trying to extract it with some pin, he destroyed its sim contact pins. But I am sure any good mobile hardware wendor would have fixed that too. So stop worrying and just try it according to the book.

Read all the problems. Simple solution

1. People who have 2G iPhone dont need any downgrade, coz its easily unlockable by quickpwn or pwnage tools.

2. People with 3G iPhone accidently or genuinely got the firmware 2.2.1
-first JAILBREAK it using quickpwn or Pwnage Tools
-then open CYDIA in iPhone
-install FUZZYBAND Downgrader
-Open it from menu, it will check the bootloader and
baseband
-if ur bootloader version there is 05.08 or 5.8 it will
tell u its downgradeable and do it and ur baseband is
2.28 and u can easily downgrade it and unlock it.
-and if ur bootloader is 05.09 or 5.9 dude u r in trouble
and ur iPhone cannt be unlocked up till today. I mean
its impossible. Sorry coz thats the weak hole Apple
covered in the bootloader to make DEV TEAM suicide.

3.People with iPod Touch 1st Generation dont need to download it, they can just jailbreak it
4.People with iPod Touch 2G shall not risk it coz i read somewhere it wont work.

People thanks for appreciations of those who wanted this info. If anyone knows more plz share. ONE THING MORE FROM ALL MY KNOWLEDE Any brick assosiated with operating system or firmware can be undone. So feel free, lifes so small for experimenting.

Wow! I would have never thought of that, I thought the reason for the error, was an effort by apple, to prevent jailbreaking and unlocking. I would have never known that the firmware was actually already installed! You have no idea how much anger I have been through trying to downgrade, had I not found this, I would have thrown my phone at the wall. Do you have a paypal? I’m broke atm, but when I get a few few bucks, I would like to donate, just email me your paypal. Thanks again.
