If you want to unlock iPhone 4 on iOS 4.3.1, here’s a good news. MuscleNerd has just announced on his twitter account that an updated version of Ultrasn0w for iOS 4.3.1 will be released later today that will allow you to unlock iPhone 4.3.1 if you’ve been able to preserve your baseband.
Here’s his tweet:
From his tweet:
BTW ultrasn0w needs an update for 4.3.1, so unlockers should wait until that gets pushed out (hopefully also today)
So, as it’s clear, the upcoming ultrasn0w 1.3 won’t support any additional basebands to unlock iPhone 4 on iOS 4.3.1 and iPhone 3GS on iOS 4.3.1 but will *just* add the support for iOS 4.3.1 so that there’s no ultrasn0w crash issues on iOS 4.3.1.
