A new version of redsn0w will be released in the next few hours

  Last week the Dev Team they promised iDevice owners that they will give them the opportunity to restore to iOS 5.x if they own an iPad 3, iPad 2 tablet (without SHSHs for iOS 4.x and 5.x) or iPhone 4S, and in this in the evening MuscleNerd confirmed that the program will be available in the following hours. Responding to a user, he stated that by the end of the day, in the US, the new version of redsn0w will be released, so by tomorrow around noon you should be able to use it to restore various iDevices, if you need to.

  Don't forget that Apple has stopped signing SHSHs for iOS 5.1.1 and you cannot restore easily or at all to this version of the operating system.
