A new version of the Apple iOS has been released and with iOS 5.1.1 there comes the task of the many hackers and the jailbreak community to provide a new jailbreak solution and a way to unlock iPhone 4 on iOS 5.1.1. The various dev teams have already begun bringing out updates to their jailbreak and unlock utilities. The new iOS doesn�t seem to have anything major in terms of changes and most of the changes are to fix bugs and provide a few performance enhancements. For those iPhone owners with older basebands who rely on the Ultrasn0w unlock there is good news. The Ultrasn0w Fixer has been updated to support iOS 5.1.1.
