iPhone hacker MuscleNerd, the brain of the iPhone Dev Team, has confirmed that their goal now is getting Monte mode to untether iOS 4.3 jailbreak when it goes public.
and now one goal is to get Monte to untether 4.3-final using 4.2.1 SHSH blobs (and future FW X->FW Y's, etc)Not only that, the Monte mode won't require iOS 4.2b3 SHSH blobs anymore as their goal is to get Monte working with the current iOS 4.2.1 SHSH blobs. So you must tap on Make my life easier in Cydia so that it will be able to save iOS 4.2.1 SHSH blobs.
While MuscleNerd said that their goal is untethering iOS 4.3 jailbreak, that means they've already finished work on the unlock and it looks like they'll release it as soon as iOS 4.3 goes public by mid this month.
Besides, we've already shared with you the news about George Hotz untethered jailbreak when Verizon iPhone 4 delivers. Wait, and have some fun!
