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 here.
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:
If you’ve updated to 4.1beta2 on iPhone3G or iPod2G(non-MC), you can use this redsn0w from June to jailbreak. Just point it at the 4.0 IPSW (the public one, not the developer GM one).
(Yes – point it at the 4.0 IPSW even though you’re at 4.1beta2).
Don’t do this if you need the ultrasn0w carrier unlock!!
Note 1: This won’t hacktivate your iPhone3G – but for those with legit access to the 4.1beta2 this shouldn’t matter. Please don’t pirate Apple software
Note 2: If you’re at 4.1beta2 you’ll probably experience network problems after jailbreaking. Until a new version of redsn0w is released, you may need to rely on afc2 access (such as FunBox-like file browser programs) to manipulate your filesystem.
Note 3: This is recommended only for power users who can deal with the problems that will pop up as the JB apps fall further behind the beta firmwares.
