Ultrasnow 1.2.1 is out now. The main purpose of this update is to support iOS 4.3.1 and fix the signal bar issue on iPhone 4. It is to inform you that this update is for current unlockers only i.e., for those users who are still on unlockable baseband.
If you are still keeping the unlockable baseband preserved, you can now safely update your device to custom t iOS 4.3.1 cooked by using either Sn0wbreeze or PwnageTool and after that install Ultrasnow 1.2.1 to enjoy any network.
- Ultrasn0w 1.2.1 works for basebands (01.59.00 / 04.26.08 / 05.11.07 / 05.12.01 / 05.13.04 / 06.15.00)
- Ultrasn0w is NOT compatible with the folllowing basebands! (02.10.04 / 03.10.01 / 04.10.01 / 05.14.02 / 05.15.04)
Update #2:
We’ve pushed out the 4.3.1 compatibility fix for ultrasn0w in Cydia — it’s now at version 1.2.1. If you’re not already at 4.3.1 and you need the unlock, please be sure you understand how to get to 4.3.1 using a custom IPSW that doesn’t update your baseband.
This isn’t a new unlock! It’s to allow those who are already unlocked to use FW 4.3.1. It also fixes the signal bar issue for those who aren’t using the unlock but retain an older baseband intentionally.
AFTER INSTALLING ULTRASN0W 1.2.1, PLEASE REBOOT YOUR iPHONE using the normal “slide to power off” swipe. T-Mobile users in the USA also should disable 3G mode in Settings->General->Network.
A big thanks to @sbingner and @ronaldsb for helping with the testing of this update!
How to Install Ultrasnow 1.2.1:
