Apple�s iOS 6 is the latest offering in their firmware and there are plenty of dev-teams out there who are spending a lot of time looking for new loopholes and gaps that Apple�s security team may have missed. This comes in the form of jailbreak and unlocking. We are happy to say that if you have iOS 6 on an iPhone 4 or iPhone 3GS you can unlock it using Ultrasn0w Fixer.
By unlocking your iPhone you will be able to use any SIM and you also get to bypass restrictions that may have been set by your carrier. If you are like many other iPhone users who have been preserving their baseband for unlocking purposes over the past couple of years, you will be more than familiar with Ultrasn0w Fixer which has now been updated for iOS 6.
Ultrasn0w Fixer for iOS 6 only works for the iPhone 4 and iPhone 3GS and it supports the following basebands:
� 01.59.00 � 04.26.08 � 05.11.07 � 05.13.01 � 05.12.01 � 06.15.00The official Ultrasn0w tool might be updated in the near future but for now this Fixer will work perfectly. Your iPhone running iOS 6 will have to be jailbroken to use this utility and at present there is only a tethered jailbreak available via Redsn0w. You also need to have preserved baseband. If you have all this, then just follow the steps below to unlock your iOS 6 iPhone.
Step 1: Launch Cydia and then hit Manage and then Sources.
Step 2: Add the iparelhos repository. You should already have this is you have re-added your sources from iOS 5, but if not, select Edit and Add and then type http://repo.iparelhos.com before hitting Add Source.
Step 3: Open the repo and browse to the Ultrasn0w Fixer for 6.0 utility. Tap the install button and let Cydia do the rest.
Step 4: Download the latest official iteration of Ultrasn0w from Cydia and install it.
You should now have an unlocked iOS 6 iPhone. You do have to make sure that you install the Fixer before you install the official Ultrasn0w utility otherwise this won�t work.
