Untethered jailbreak for iOS 4.3.1 available today according to MuscleNerd

MuscleNerd confirmed a few minutes ago that the new untethered jailbreak solution will be released today. "Funday" is the term used by the Dev Team for Sunday, meaning Sunday because on this day they have the habit of releasing jailbreak solutions. Of course, they are now still testing the solution and will launch it according to US time, that is, sometime during the night here. Whether it will be available before midnight or after midnight, we will have a jailbreak solution in less than 0 hours! It is not known if tonight we will have PwanageTool for iOS 00, redsn0w or both, but I think that PwnageTool will be the first available solution.

UPDATED: It seems that eventually both redsn0w and PwnageTool will be available.
UPDATE 2: If you have an iPad 2, do not update to iOS 4.3.1 because the jailbreak vulnerability is found in iOS 4.3.
