iOS 5.1.1 Untethered Jailbreak Tutorial
The wait for the highly anticipated untethered jailbreak for iOS 5.1.1 ended on the 25th of May. Important members of the Chronic Dev Team announced the second version of Absinthe made by the GreenPois0n team. They made this announcement at the Hack in the Box (HITB) security conference which was held in Amsterdam. This tool has been named Absinthe 2.0.
The other startling news was that Apple also released a new revised version of the iOS 5.1.1 and the new build was labelled 9B208. The name of the earlier build was 9B206. This new revised edition was released especially for the iPhone 4 GSM and only fixed a small bug. Apple warned Jailbreaking users to avoid updating to the latest firmware version in case that they might lose their jailbreak as the current version for jailbreak did not include the revised firmware update. This threat has been rectified by the Chronic Dev Team and iOS hacker iH8Sn0w by releasing Absinthe 2.0.2 and Sn0wbreeze 2.9.5 respectively. They will add iOS 5.1.1 9B208 support for iPhone 4 GSM.
