How to Unlock iPhone 2G with OS 3.0 GM Gold

10 June 2009 by Vinay 24 Comments

First of all it’s confirmed OS 3.0 doesn’t updates your iPhone Baseband. So if anything goes wrong you can downgrade your firmware any time “ How to Downgrade iPhone 3G / 2G 3.0 back to 2.2.1 “ I have tried different tricks but only this one is the most successful trick. In the following tutorial we have two options if you used Pwnage (Mac Tool) in the Past don’t worry do a simple update as described in procedure two given below. But if you have used QuickPwn (Windows tool) in past please follow the first procedure it requires restore-downgrade-update trick. The reason behind downgrading is QuickPwn 1.0 works like Pwnage Tool. It will be very hard for you to find QuickPwn RC3 so we managed all the downloads you need in the end of this post. This guide is based on my personal experience and i am using this trick to preserve my unlock while updating to beta releases too. With this trick i’ve successfully tested up to OS 3.0 Beta 4. However i’ll be not responsible for any damage (if any!).

Update Forget GM because OS 3.0 final is here check the latest here :

Unlock iPhone 2G OS 3.0 7A341 Final Version

For 3G Users : This guide is not for you, Don’t try it will lose your unlock if you UPDATE or RESTORE to 3.0, cause the baseband is also updated permanently.

For 2G Users : You can do whatever you like (UPDATE, RESTORE,DOWNGRADE), that you wont lose your unlock. Cause the baseband stays the same, its not updated.

iPhone 2g 2.2.1 QuickPwned to 3.0 on Windows Computer :

Fire iTunes 8.0, connect your iPhone 2G, do a Restore install (option-Restore button) to firmware 2.0.2 Using DFU Mode.
Run QuickPwn RC3 and allow it to pwn the iPhone using firmware 2.0.2. It should finish activated.
Using iTunes again, set it up as a new iPhone (do not restore from backup).
Now install iTunes 8.2 final because OS 3.0 is supported by iTunes 8.2 final version only.
Now update by click option-Update button (NOT Restore), and choose the firmware 3.0 image.

iPhone 2g 2.2.1 Pwned to 3.0 Beta on Mac OS X :

Make sure your iPhone 2G is Pwned 2.2.1 (Pwnage NOT QuickPwn) if sure fire iTunes.
Now update by click option-Update button (NOT Restore), and choose the firmware 3.0 image.

PS : I have downgraded back to 2.2.1 and waiting for OS 3.0 final release. I hope Dev team release Jailbreak for 3.0 very soon.

It takes my lot of hours to test this guide but it takes yours only 1 minute to digg the story kindly consider.

Hi,

Thanks for the guide, I have one problem. You say this: “Run QuickPwn 1.0 and allow it to pwn the iPhone using firmware 2.0.2. It should finish activated.” It is under the title: “iPhone 2g 2.2.1 QuickPwned to 3.0 on Windows Computer :” But the QuickPwn 1.0 in the download is for the Mac! How can I use this on a Windows PC?

Thanks

@ taranfx It seems you have Pwned your iPhone or your iPhone is unlocked with custom firmware. This complex guide is for the peoples who used Qucikpwn 2.2.5 to unlock their iPhone.

@ppsss @ramon Thanx for pointing the error the download link is changed to Quickpwn RC3 for Windows

itunes 8.2 changed the way it puts apps on the iphone, so if the apps they were not purchase it probably won’t work and I also notice some of the free apps I downloaded from the store dont work either I think the developers have to update programs to work with the new 3.0 firmware

Diego

you didnt unlock and iphone properly, thats why you have that message.
I think you’ll have to start over again go back to itunes 8.0 restore back to 2.0.2 and do the process again
