Ultrasn0w was updated to support old baseband on new iOS 4.3.3.
Here is the list of supported basebands:
Ultrasn0w 1.2.3 (for unlockers with old baseband) is available in Cydia.
You can update to iOS 4.3.3 and preserve old baseband using two utilities. Here are step-by-step instructions:
PwnageTool 4.3.3.1 (Mac OS)
Sn0wBreeze 2.7.3 (Windows)
DevTeam released much anticipated untethered jailbreak for the latest iOS 4.3.1 – RedSn0w 0.9.6 rc9 and PwngeTool 4.3.
The 4.3.1 untether works on all Apple devices that support 4.3.1 except for the iPad2:
Redsnow is easy to use, it is available for Windows and Mac OS. Pwnagetool can be used to create custom ipsw and preserve baseband, it supports Mac OS only.
You can download RedSn0w 0.9.6 rc9 here and PwnageTool 4.3 here.
Here are our tutorials:
Ultrasn0w doesn’t work on iOS 4.3.1 yet (even with iOS 4.3.1 + old baseband). The fix will be available soon. Here’s a warning from DevTeam for unlockers:
DevTeam recently released new version of redsn0w to jailbreak iOS 4.1. New RedSn0w 0.9.6 b1 supports iOS 4.0 and iOS 4.1 running on iPhone 3G or iPod touch 2G.
There is only Mac OS X x86 version, that you can download .
Redsn0w is easy to use:
As usual DevTeam reminds us:
IF YOU USE THE ULTRASN0W UNLOCK, PLEASE WAIT FOR PWNAGETOOL TO SUPPORT 4.1. DO NOT USE REDSN0W
That’s because to use redsn0w at 4.1, you need to already have updated to official 4.1 from Apple. If you do that, you lose the ultrasn0w unlock (possibly forever).
MuscleNerd tweeted today that the recent redsn0w utility is able to jailbreak the iOS 4.1 beta2 on iPhone 3G and iPod Touch 2G. This is useful for developers only, however good news for everyone.
Here’s some info from the DevTeam wiki page:
