iH8Sn0w has released Sn0wbreeze 2.4b1, and the Windows jailbreak tool will now jailbreak iOS 4.3.1. There’s already been a tethered jailbreak for 4.3.1 uncovered in PwnageTool, and both available jailbreaks are still tethered.

Sn0wbreeze is now the more stable option for jailbreak iOS 4.3.1, but there is still no untethered solution available. Jailbreak devs are working hard to release an official untethered jailbreak for the latest version of iOS, but there is no exact ETA set.

We recommend holding off on the latest Sn0wbreeze beta until an untethered solution is available. If you’re still itchy to jailbreak 4.3.1, RedmondPie has put together a tutorial on how to jailbreak iOS 4.3.1.

Here are the release notes for Sn0wbreeze 2.4b1:

  • ultrasn0w now 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)
  • iOS 4.3.1 is now supported. • iPhone 3GS users can upgrade to 06.15.00 baseband now under Unlocks section in Expert.
  • Upgrading your iPhone 3GS baseband to the 06.15.00 iPad baseband hack to unlock MAY cause you to lose your GPS!

If you want to keep your unlock, make sure your baseband is compatible with the latest beta of Sn0wbreeze.

You can download the latest beta here. The developer’s page contains the release notes.

  • Seven

    So for 3gs old bootrom is untethered ?

    • Ryan

      Don’t quote me, but mine is. I don’t know how, or why. I had to restore it really weird, because my Power button is broken, and I had to restore to a custom, hacked 3.1.3 firmware to cause it to enter DFU Mode. Then, I used that DFU Mode to restore to my cooked Sn0wbreeze 4.3.1 firmware. So, when I installed WinterBoard, and my phone restarted, I expected to have to do some cooky thing to make Cydia work, but… it just worked. I can make a video if I must.
