Just after the release of iOS 5.1, the chronic dev team released redsn0w to jailbreak iPhone, iPod Touch or iPad [N0n-A4] devices. Although, it is a tethered jailbreak for iOS 5.1 but many users still jailbroke their iPhone. If you are one of those and want to unlock your iPhone 3Gs or iPhone 4 using ultrasn0w, you can follow this tutorial to unlock your iDevice.
An updated version of ultrasn0w is not released yet but zmaster has released Ultrasn0w fixer to sort out this problem. This software is not released publically but you can find it on the developer’s repository. Currently, this only supports for older basebands such as 01.59.00, 04.26.08, 05.11.07, 05.13.01, 05.12.01, 06.15.00.
