We have recently reported that ultrasn0w is broken on new iOS 4.3.1 and didn’t work directly until you use the Ultrasn0w fixer to patch the ultrasn0w to work on latest iOS 4.3.1 firmware, but now as the time getting closer to the release of untethered jailbreak, the things regarding about exploit coming out. This time MuscleNerd says, that now ultrasn0w originally updated to the next version which will solve the broken status of ultrasn0w on iOS 4.3.1

 

Musclenerd Says:

BTW ultrasn0w needs an update for 4.3.1, so unlockers should wait until that gets pushed out (hopefully also today) (1:17 AM) (link)

The ultrasn0w update won’t be a new unlock, but 4.3.1 FW itself breaks current ultrasn0w (unintentionally) [1:17 AM] (link)

 

The new update of ultrasn0w it does not mean to a new unlock exploit or will work on new basebands it just fix the broken status of ultrasn0w 1.2 and also if the ultrasn0w is updated than don’t need to use the ultrasn0w fixer.
