Dev Team Releases UltraSn0w iPhone Unlock for iOS 4.3.1

Sébastien Page ∙ April 9, 2011

As expected the Dev Team released tonight an updated version of their UltraSn0w unlock for iPhone 4.3.1. As we noted before, this version of UltraSn0w will not unlock any new baseband. UltraSn0w 1.2.1 will unlock the iPhone 3GS or iPhone 4 on baseband 01.59.00, 04.26.08, 05.11.07, 05.12.01, 05.13.04, and 06.15.00.

If you are on any of these basebands, you can update to iOS 4.3.1 while preserving your baseband using PwnageTool. If your baseband is different from the one listed above, I'm afraid there is no unlock for you at this time...

How to Update to iOS 4.3.1 and Preserve iPhone 4 1.59.00 Baseband [Tutorial]

Guest Author ∙ Updated February 24, 2017

Now that Redsn0w 0.9.6rc9  finally provides the long awaited iOS 4.3.1 untethered jailbreak, many iPhone 4 owners with unlocked iPhones’ have been advised to hold off upgrading to 4.3.1 as you will lose the ability to unlock, since the newer firmware will update your baseband.

Furthermore, as we've mentioned earlier this morning, the new iOS 4.3.1 firmware currently is incompatible with the Dev Team's ultrasn0w unlock tool. It is recommended that you wait for the Dev Team to update this tool before upgrading and jailbreaking.

But for those anxious to update to the new iOS 4.3.1 firmware and still preserve their iPhone 4 1.59.00 baseband so they can be guaranteed an unlock when the Dev Team updates their ultrasn0w tool, follow our tutorial below.

More Details About iPhone 4.3.1 Unlock Emerge

Jeff Benjamin ∙ April 3, 2011

Just to preface this before anyone gets the wrong idea; there is still no new baseband unlock available.

Now that the formalities are out of the way, I think it's safe to tell you that new details have been revealed about the existing baseband unlock and its compatibility with the soon to be released untethered jailbreak for iOS 4.3.1.

Depending on when the jailbreak is actually released, if you rely on an unlock, you may have to wait a while until a new version of UltraSn0w is released. This is due to some compatibility issues between iOS 4.3.1 and the current version of UltraSn0w.

Fortunately, you won't have to wait long, as the latest tweets from members of the iPhone Dev Team confirm...
