Then iPhone Dev Team already released the latest version of Ultrasn0w iPhone carrier unlock tool with iOS 4.3.1 support to unlock jailbroken iPhone 4 and iPhone 3GS with old baseband version.
Here’s the official announcement of the iPhone Dev Team regarding their new software:
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.
ONLY Supported basebands: (01.59.00 / 04.26.08 / 05.11.07 / 05.12.01 / 05.13.04 / 06.15.00.
As quoted above, Ultrasn0w 1.2.1 is not a new unlock and it will not unlock new baseband, but it does allow you to maintain your carrier unlock while upgrading to jailbroken iOS 4.3.1 using PwnageTool 4.3 for Mac Os X or Sn0wbreeze 2.5.1 for Windows to preserve the unlockable baseband of the device.
The new UltraSn0w 1.2.1 has capability to unlock iPhone 4 and iPhone 3GS on baseband 01.59.00, 04.26.08, 05.11.07, 05.12.01, 05.13.04, and 06.15.00. iPhone 3GS user need to update the baseband of their device to iPad’s 6.15.00 in order to unlock. So any baseband that is not listed here is not unlockable. You can check the baseband version of your iPhone 4 or iPhone 3GS Settings -> General -> About.
