Upgrade/Downgrade to/from iPhone OS 3.0 Final Build

// June 15th, 2009 // Life's Happenings, iPhone

Ive been using the iPhone for quite some time now, right from the good old OS 1.1.1. Since iPhones were not available in India that time, I had an unlocked and jailbroken 2G. Gradually, I went on upgrading to the newer OS’s till 1.1.4. Then after quite some time, I decided to try my hand at doing the Jailbreak and unlock myself. So when OS 2.0 came along, I read up tutorials and forums successfully migrated to 2.1 with the unlock in place and of course, Cydia and Installer. The WWDC saw the launch of the new OS 3.0 with a plethora a new features (albeit, after 5 beta versions). I never tried to use the beta versions since they required one to have the UDID registered, and I could not get my hands on one.

Then I came across @aryayush’s post via Twitter and decided to follow it. But I overlooked one tiny instruction that said click Shift+Update and not Shift+Restore, and though the OS change did happen, since I had restored it, I lost the unlock and had no way to unlock it. The official iPhoneDev tools are still a few days away. I tried all the possible suggestions available on the net, but non worked. Coz apparently Apple says the new OS 3.0 cannot be downgraded. Well, one some site, I don’t remember which, I found a suggestion that at first I thought didn’t make sense.

Try using iTunes 8.0/8.1, put the phone in DFU mode and then restore to 2.0.2. Now I had tried restoring to 2.2/2.2.1 etc and even to 1.1.4. None worked. I thought even this might be no exception. But out of sheer desperation to get the phone working again, I tried it. Yes it worked. Woohoo!

So now, being extra careful, I unlocked 2.0.2 using QuickPWN RC3 and then updated to 2.2.1. Then making sure the unlock was stil lin place, updated to 3.0 7A341. Success met me at last and now I have the iPhone running 3.0 OS. I love the spotlight feature and the copy paste of course. Here are a few screenshots :

Home Screen Spotlight

Spotlight Search 3.0 7A341

Copy Paste Messages Management

Call Management Voice Memos

Now I wait for the iPhoneDevs to come up with QuickPWN for 3.0…

Happy iPhoning…

    You first need to upgrade to 2.0 and then to 2.2.1. After which you can go up to 3.0. But be careful.
    If you need to know in detail how to do it, check out the tutorials on iClarified.com. They’re very helpful. In case of any difficulty, let me know.
    But one word of advice, don’t try the procedure unless you’re absolutely sure of it. Else you’ll be spoiling expensive equipment.

    Hehe you must have got quite a scare…but dont worry dude…2G iPhones have nothing to worry as the 3.0 Update doesn’t upgrade the Baseband. So your phone can be Unlocked no matter which firmware you’re on.

    @russell : Just go to 3.0 anyhow…and use “Redsn0w”. Follow :

    @Tanmay
    Of course. Got a scare for a few hours. Though I had bricked it and might have to wait till QuickPWN (didnt know redsn0w will come in its place) comes. But yes, downgraded and problem solved. 3.0 up and running flawlessly…
