Following the release of the updated PwnageTool 4.3.2 jailbreak tool, the iPhone Dev Team has also pushed out an update to the UltraSn0w unlock in Cydia.
UltraSn0w 1.2.2 has been released to support the new iOS 4.3.2 firmware, as the previous version of UltraSn0w (1.2.1) was broken in iOS 4.3.2. Please note, this will only work for the older iPhone 4 baseband 1.59.00, and iPhone 3G/3GS basebands 4.26.08, 5.11.07, 5.12.01, 5.13.04, and 6.15.00. It can not unlock newer basebands since there is currently no unlock available.
The Dev Team has provided the following information on their blog…
“Note that there’s a corresponding update to ultrasn0w, which has been bumped up to v1.2.2 to get along with iOS 4.3.2 (the ultrasn0w update does not include any new baseband support!). Please reboot your iPhone using the normal “slide to power off” swipe after installing ultrasn0w 1.2.2.”
The Dev-Team has updated ultrasn0w to version 1.2.1, which brings unlocking support to iOS 4.3.1. Please note that this is not a new ultrasn0w, but rather an update to bring 4.3.1 compatibility to existing unlockers. Users will need to use either PwnageTool or sn0wbreeze to cook an IPSW with a preserved baseband (01.59.00, 04.26.08, 05.11.07, 05.12.01, 05.13.04 or 06.15.00). This update also fixes the signal bar issue for users who are on older basebands.
Ultrasn0w can be found on Cydia under the http://repo666.ultrasn0w.com repository.
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. There are lots of guides for this (like at iClarified.com).
This isn’t a new unlock! It’s to allow those who are already using ultrasn0w 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 we posted Unlock 2.10.04 / 3.10.01 News ! Today MuscleNerd has just announced on his twitter account that he’s going to release a new ultrasn0w today along with the untethered jailbreak on iOS 4.3.1.
BTW ultrasn0w needs an update for 4.3.1, so unlockers should wait until that gets pushed out.
