For those unaware- unlock is a method allowing any SIM to be used on a smartphone – bypassing restrictions usually beset by a carrier. Majority of iPhone enthusiasts strive to have their devices non-dependent on the carrier operators, who usually offer a way for older smartphones to be unlocked.
However, there’s an unlock solution for your iPhone 4 and 3GS running latest version of Apple’s mobile OS as well, available via the well-known jailbreak utility called Ultrasn0w Fixer, updated for iOS 6. However the Ultrasn0w Fixer for iOS 6 supports certain basebands, including:
Despite the official Ultrasn0w being weeks away, this Fixer will not let you down till then. However, make sure your iOS 6 device is jailbroken of course with preserved baseband before getting started.
So here’s the deal – open Cydia, navigate to Manage > Sources and add iparelhos repository by selecting Edit and add and typing the following link type - http://repo.iparelhos.com before hitting Add Source. Those organized users who re-added their sources from iOS 5 should omit this step.
You’ll now need to download the latest official iteration of Ultrasn0w from Cydia, but please make sure you install the official Ultrasn0w first BEFORE installing the Fixer, otherwise it will not be fully functional. So now you’re a step away from having an unlocked phone – just browse for Ultrasn0w Fixer for 6.0 utility in Cydia, tap the Install button and let Cydia work its magic!
That’s it! Do not forget to come back and share your unlocking experiences in the comments below!
