The 4.3.3 untether works on all Apple devices that support 4.3.2 except for the iPad2:
iPhone 3GS
(GSM)
iPod Touch 3G
iPod Touch 4G
iPad 1
AppleTV 2G (PwnageTool only for now)
Redsnow is easy to use, it is available for Windows and Mac OS. As usual for unlockers – do not update to 4.3.3, use PwnageTool (MAC) and Sn0wBreeze (Windows) to preserve the baseband.
You can download RedSn0w 0.9.6 rc15 .
You can download PwnageTool 4.3.3 .
Ultrasn0w was also updated to support old baseband on new iOS 4.3.3. Ultrasn0w 1.2.3 (for unlockers with old baseband) is available in Cydia.
New tutorials are on it’s way. For now you can still use our tutorials for iOS 4.3.1. Just download iOS 4.3.2 , update in iTunes, point redsn0w to it, everything else is the same:
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.
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:
Good news everyone. DevTeam recently posted a tweet where they inform us that they will soon release a new version of Redsn0w utility for Windows. It will be an untethered jailbreak for iOS 4.2.1 using the Monte iOS 4.1 technique.
In fact, Apple still provides 4.1 ipsw and this could be used to jailbreak.
In addition, the team warns that Windows version will be very slow because the program uses the filesystem instead of RAM.
