Finally, this should put big smiles on your faces. Its been a very long and painful journey for all you guys who got stuck on baseband 05.14.02 or 5.15.04 after the iOS 4.1 or iOS 4.2.1 update. But this definitely gave you a lesson to remember and I am sure most of you will either never touch that iTunes Evil popup or talk to me first about it. You guys have come a long way, I must appreciate the patience.
The Dev Team released the Ultrasn0w today and very complicated way of unlocking an iDevice. But, its not that hard, but its just a bit different from the older and easier ways of Jailbreaking and Unlocking. The trick is to create a new baseband (06.15.00) and then unlock it instead of unlocking 05.14.02 or 5.15.04. I guess they did not have any luck unlocking those basebands so they had to come up with a new plan.
Here is a Step by Step Guide:
Very Important: You need to Jailbreak and update your Baseband on your iPhone 3GS and 3G first, use the guide posted here if you are on a MAC. PC users can use Redsn0w, here is the guide. This is a very important step, you can not move forward without Jailbreaking and updating your baseband to 06.15.00, so follow the links mentioned and carefully jailbreak your device.
Once you are done with the Jailbreak, look for Cydia on your iPhone screen.
- Tap on Cydia to run it.
- Go to the “Manage” section.
- Tap the “Sources” button
- You can also go straight to Search tab and type in “ultrasn0w”. if you find it just tap on it and install it and skip rest of the tutorial.
Go to “Edit” and then “Add”. A Popup box will appear, now enter this URL Source in it “http://repo666.ultrasn0w.com” and tap on “Add Source”. This should update Cydia by adding this URL source.
Once this source is in, go to the search tab and type “ultrasn0w”. An application should show up, tap on install at the top. This application will unlock your iPhone 3GS or 3G on baseband 5.14.02 or 05.15.04 and you can now use your device on any carrier.
Restart your iPhone and enjoy the unlocked iPhone 3GS or 3G or iOS 4.1 or iOS 4.2.1.
