iOS 4.2.1 Unlock is Fully Working on iOS 4.2.1 and WILL Be Released on Sunday For iPhone 3G, 3GS

A lot of things happened while I was out of the state celebrating Thanksgiving with my family. One of the very important updates / news is for all UNLOCKERS out there.
Yesterday MuscleNerd has announced that UltraSn0w is now fully working on iOS 4.2.1. The iPhone Dev-Team has made good progress on the iOS 4.2.1 unlock and it should be available by Sunday for the iPhone 3G and 3GS.
NOTE: The iPhone 4 unlock will require a bit more time, according to MuscleNerd.
Finally got ultrasn0w working fully on 4.2.1. Apple inadvertently(!) broke ultrasn0w via aggressive compiler optimization

MuscleNerd previously announced that the UltraSn0w unlock should be available by Sunday for the iPhone 3G and iPhone 3GS. The unlock for the iPhone 4 will take some more time.
Good progress today…everything is on track for updated ultrasn0w by Sunday/Funday at the latest (longer for iPhone4!)
Happy Thanksgiving Everyone! (Please don’t wait out today for the unlock, we celebrate Thanksgiving with family too!)

We’ll keep you updated with more information as it becomes available.
