Well we have another redsnow upgrade this time giving those users with the build “9A406″ ability to downgrade. The build number is associated with iPhone 4S, giving them ability to downgrade to firmware iOS 5.0.1. The one that can be jailbroken untethered.
Yesterday redsnow received a major upgrade. For the first time ever it gave users of the jailbreaking tool redsnow ability to downgrade A5 devices, these include iPhone 4S, iPad 2 and the new iPad 3.
Users with build 9A406 were accidentally left out of this amazing feature but now this new version of redsnow gives those users the feature they were missing out on.
Download Redsnow 0.9.11b2
Download Redsnow 0.9.11b2 Mac

Those users who have already downloaded the previous version that was redsnow 0.9.11b1, there is no need to download this version unless you were facing problems or you had the build 9A406 iPhone 4S.
To use the new feature that is downgrading your firmware simply install redsnow and navigate to Extras->Even More->Restore.
