iPhone Dev team has just released a new version of Redsn0w and PwnageTool, which includes Rocky Racoon and untethered iOS 5.1.1 jailbreak developed by pod2g and planetbeing that was used in Absinthe 2.0.x jailbreak.
If you were having problems jailbreaking your iOS device with Absinthe 2.0.x then you could try again using Redsn0w 0.9.12b1.
If you’ve already jailbroken your iOS device using Absinthe 2.0.x, iPhone Dev team’s CLI tool or the Rocky Racoon 5.1.1 Untether, then you don’t need to use Redsn0w or PwnageTool.
iPhone Dev team have provided the following information about Redsn0w 0.9.12b1 on their blog:
redsn0w allows owners of A4+earlier devices to install rocky-racoon two different ways:
- backup/restore method similar to Absinthe and cinject
- its traditional limera1n-based ramdisk install. If you have a lot of media on your A4 device (music, movies, TV shows, etc), then the ramdisk method is preferrred because it avoids any possibility of later problems related to syncing to iCloud (including Photo Stream and Music Match). The ramdisk method is not available for A5 devices or later because limera1n can’t be used. If you’d like to use redsn0w’s ramdisk method, just be sure to put the A4 device in DFU or Recovery mode before starting redsn0w (otherwise it will immediately start to use the backup/restore method).
PwnageTool 5.1.1 allows users who depend on Ultrasn0w to unlock their iPhone, to create and update iPhone with custom pre-jailbroken iOS 5.1.1 firmware file to preserve the baseband. PwnageTool is available only for Mac users. iH8sn0w had released Sn0wbreeze 2.9.5 for Windows users.
Dev team has also released an updated version of Ultrasn0w (v1.2.7), which now supports iOS 5.1.1 that can be installed after preserving baseband with PwnageTool or Sn0wbreeze.
