UltraSn0w unlock by the iPhone Dev Team is a software unlock for iPhone. Our guides and tutorials will show you how to unlock your iPhone with UltraSn0w.
Not even a week after iOS 4.2.1 was released, and following the update of the RedSn0w jailbreak, the Dev Team delivered today an update to their UltraSn0w unlock for iOS 4.2.1.
This unlock will work for the iPhone 3G or iPhone 3GS with baseband 04.26.08, 05.11.07, 05.12.01, or 05.13.04. It will also work with iPhone 4 with baseband 01.59.00...
A couple days ago we informed you that the UltraSn0w unlock for iPhone iOS 4.2.1 was supposedly going to drop this Sunday. According to a recent tweet from Dev Team member MuscleNerd, it seems we are on the right track for a release on schedule.
This UltraSn0w unlock for iOS 4.2.1 will work with the iPhone 3G and 3GS. It will not work with the iPhone 4 yet, but it's being worked on...
Some very comforting news on this cold Thanksgiving day, as MuscleNerd confirmed today that the iPhone unlock for iOS 4.2.1 will most likely be released this Sunday or even before.
This is good news, especially for those of you who still are using an iPhone 3GS or 3G. It is however not as good news for iPhone 4 users because there won't have an unlock for iPhone 4 for a little while...
Technically, it's not possible to unlock an iPhone that has been updated to iOS 4.1 because there is no unlock available for the iOS 4.1 baseband. Now depending on your situation, there might be a way to unlock your iPhone.
If you are still on iOS 4.0.1 (or even earlier version. ie 3.1.3), then you can use PwnageTool to jailbreak your iPhone while preserving the baseband (see our guide here). This will make sure you update to the latest iOS version but don't update the baseband, which is the key part in unlocking your iPhone...
We just gave you the bad news that there won't be an iPhone 3GS iOS 4.1 jailbreak, and unfortunately, we have more bad news, especially for unlockers. According to iPhone hacker Veence, there will not be an unlock for any baseband on iOS 4.1.
So why is that? I've got my ideas...
Looking to unlock your iPhone running iOS 4.1? We've got some good news and some bad news for you... Let's start with the bad news, shall we?
The bad news is that if you've already updated your iPhone to iOS 4.1, you will not be able to unlock it, at least for the time being. MuscleNerd confirmed that UltraSn0w will not work on any iOS 4.1 baseband and that you cannot downgrade to a previous version.
And now for the good news...
This step by step guide and tutorial will show you how to unlock your iPhone 3G iOS 4.0.2 using UltraSn0w 1.1-1. At the time I am writing this, it will only work with the iPhone 3G since there is no jailbreak for other devices.
Step 1: Jailbreak your iPhone 3G using RedSn0w.
Step 2: Go to Cydia and search for UltraSn0w. If it’s not there, you might have to add the following repo: repo666.ultrasn0w.com
Step 3: Install UltraSn0w.
Step 4: Reboot your iPhone.
You're done. You should now be able to use your iPhone 3G with any carrier.
Some quick stats for you about the UltraSn0w unlock for iPhone. According to the Dev Team, UltraSn0w was used to unlock 784,974 iPhones within the last 5 days. That's huge! Wondering what countries are the largest users of UltraSn0w? Have a look at the numbers above. USA is #1, followed by China and Germany.
This guide and tutorial will show you how to unlock your iPhone 4 running iOS 4.0.1 using UltraSnow 1.0-1. This method will not only work with the iPhone 4 but also with older models. UltraSnow 1.0-1 will unlock:
The iPhone 3G, iPhone 3GS, and iPhone 4 Basebands 01.59.00, 04.26.08, 05.11.07, 05.12.01 and 05.13.04Note that UltraSn0w will work no matter what your iPhone model number is.
In order for UltraSn0w to work, your iPhone must be activated. If it isn't, follow these instructions to activate your iPhone without the original SIM card.
Step 1: Jailbreak your iPhone using JailbreakMe.
Step 2: Go to Cydia and search for UltraSn0w. If it's not there, you might have to add the following repo: repo666.ultrasn0w.com
Step 3: Install UltraSn0w.
Step 4: Reboot your iPhone.
Done! Your iPhone should be unlocked. You can now pop in any SIM card. If you unlocked an iPhone 4, you might have to trim the new SIM so it fits in the tray.
Because the iPhone doesn't support T-Mobile's 3G frequencies, T-Mobile users in the US should turn off 3G in Settings > General > Network.
After a long expectation, the Dev Team just released an updated version of UltraSn0w that will unlock the iPhone 4 as well as the iPhone 3G and 3GS running iOS 4.0.1.
After the JailbreakMe jailbreak released this weekend, the UltraSn0w 1.0-1 carrier unlock is the cherry on top. It is compatible with the iPhone 4 baseband 01.59.00 and the iPhone 3G/3GS basebands 04.26.08, 05.11.07, 05.12.01 and 05.13.04.
You should see UltraSn0w in Cydia under the repo666.ultrasn0w.com repo.
Good job, Dev Team! Good job.

Now that the iOS 4 jailbreak has been released, those of you who were waiting for an unlock can unlock their iPhones with UltraSn0w. Before getting into the details, let me tell you more about who this is for and who this is not for.
The latest version of ultrasn0w will unlock the iPhone 3G and iPhone 3GS running iOS 3.1.2 or higher. As long as you are running iOS 3.1.2 or up to 4.0.1, you're good.
This being said, ultrasn0w will not unlock the iPhone 4 at the time being. The Dev Team needs a little bit more of time to test out the iPhone 4 unlock before releasing it. I believe they will release the iPhone 4 unlock in the next few days, so stay tuned.
This guide and tutorial will show you how to unlock your iPhone 3GS or iPhone 3G running iOS 4 using ultrasn0w.
Step 1: Make sure your iPhone is backed up in iTunes.
Step 2: Jailbreak your iPhone using JailbreakMe (see instructions here).
Step 3: After the jailbreak process is done, go to Cydia and search for ultrasn0w.
Step 4: Install ultrasn0w and reboot your iPhone.
Step 5: Done!
You now have an unlocked iPhone 3G or 3GS.
The latest firmware update that brought us iOS 4.0.1 did not update the baseband which remains at version 05.13.04. This means that if you have an iPhone 3G, you can jailbreak iOS 4.0.1 and unlock your it with UltraSn0w.
Step 1: You will have to jailbreak your iPhone 3G iOS 4.0.1 first.
Step 2: Then simply add this source to Cydia: http://repo666.ultrasn0w.com. More details here.
Step 3: Finally, search for "UltraSn0w" in Cydia and install the application. Reboot your iPhone, and you're done. You can now use your iPhone on a different carrier.
There is no iOS 4 jailbreak for iPhone 3GS and iPhone 4 yet but I guess it's just a matter of time now.
