Are you one of those folks who depends heavily on an iPhone 4 / 3GS unlock, but made the unsafe trip toward iOS 5.1.1 territory? Worry no more, as the hard-working Dev-Team's come through yet again, delivering its newest version of ultrasn0w to help alleviate your carrier lockdown problems. Version 1.2.7 of the unlocking method is friendly with iPhone 4s (nope, not the 4S) on baseband 01.59.00, while the older 3G / 3GS slabs will have to be on 04.26.08, 05.11.07, 05.12.01, 05.13.04 or 06.15.00. To go along with the latest ultrasn0w release, the Dev-Team also outed a fresh copy of RedSn0w (0.9.12b1) for both Windows and Mac, making it easier for devices sporting Cupertino's A4 chip -- and other earlier ones -- to adopt and restore using an untethered solution. All in all, we'd say it's a pretty good day for the jailbreak scene.
