Hi All,

I have an iPhone 3G 8GB, firmware 2.2.1 baseband 02.30.03 which I want to unlock. Which is the best known reliable unlock procedure?

From my search, I have found that this particular firmware and baseband cannot be unlocked. My options,

1. I need to update to OS 3.0 and use Ultrasnow to unlock.
2. Buy some SIM solution
3. Buy Software solutions from other websites like iPhoneunlocking (scam?)

Which of the above would you suggest?

Any reply will be greatly appreciated.

This needs to be posted in the iPhone Modifications forum.

Thanks, chris.

I can answer this for you, rajkumarkarthic, I just wanted to ensure it was in the proper place for other members to view/reply to it.

Anyway, what you'll want to do, IMO, if upgrade your iPhone to OS 3.0 and perform a jailbreak via redsn0w (my preference) and then unlock your iPhone with ultrasn0w, which is available in Cydia by adding this to your sources: repo666.ultrasn0w.com

KabaModern,

Sounds good. Is there any forum message with a step by step procedure? I can find one online but just wanted to be sure it worked for people.

Thanks for your prompt response.

First question to you is when you upgrade to 4.1 did you preserved the baseband. Technically you screwed if you didn't preserved the baseband. Check the modem firMware on your phone.. Setting-General-About, Scroll all the way down. You are using 3g and running 4.1. It should have 5.14.02 baseband. You would have to wait until 4.2 officially released. Unlock for this baseband will followed after 4.2 is realeased.

FYI. You can downgrade the firmware all you want, but NOT THE BASEBAND. People often mistaken between the firmware and baseband.

Sn0wbreez and iREb only jailbreak 3g/s, it does not unlock your iPhone.

As it's an iPhone 3G, it can be unlocked on the latest firmware - iOS 4.2.1. You don't need to downgrade the baseband.

Update to 4.2.1 via iTunes. Then download Redsn0w from the Dev-Teams blog and jailbreak the device (this will be an un-tethered jailbreak). Once you have jailbroken the iPhone install 'Ultrasn0w' (without quotations) through Cydia. The 0 in Ultrasn0w is a zero.

You will have a nice unlocked iPhone 3G :p
