MuscleNerd has tweeted that an updated version of Ultrasn0w would be released tonight. The unlock 4.3.1 will be compatible with iPhone 4 and iPhone 3GS. Using this update, users will be able to first upgrade to 06.15 Baseband and then would be able to downgrade to 05.13 Basebands. This surely is an important update as users on Basebands 05.14, 05.15, 05.16 don’t have any Unlock available till now. These users would be able to update their Basebands to 06.15 and then can downgrade to 05.13 for an Unlock.
This is what MuscleNerd has updated on his Twiiter account:
From his tweet:
4.3.1-compat ultrasn0w update for *current unlockers* is out to external testers. Barring any hiccups, release is tonight
@macOSxandiOS for those at 05.14, 05.15 or 05.16 I really don’t see an unlock coming. Rather, it’ll be: update to 06.15, then down to 05.13
@macOSxandiOS (because the downgrade from 06.15 goal is much higher priority than explicit 05.14,05.15, or 05.16 unlock. Achieves same.)
Those who are waiting for a stable unlock on iOS 4.3.1 BB – 1.59 should wait for some more time. The ultrasn0w 1.2.1 is already out to external testers before it is made public. If everything goes well, we will be definitely able to see the release later today.
