Redsn0w and PwnageTool for iOS 4.3.1 Untethered Jailbreak released
As promised today, that iPhone Dev-Team will release Untethered Jailbreak Tool for iOS 4.3.1 before Monday. Well, here they are, redsn0w 0.9.6 RC 9 and PwnageTool 4.3.
You can jailbreak iOS 4.3.1 untethered for iPhone3GS, iPhone4 (GSM), iPod touch 3G, iPod touch 4G, iPad1 and AppleTV 2G (by PwnageTool only for now).
Three years ago (almost to the day!), the first version of PwnageTool was released for firmware 1.1.4. So today we‚Äôre excited to release another edition of both PwnageTool and redsn0w to bring an untethered jailbreak for Apple‚Äôs latest firmware, FW 4.3.1.
WARNING WARNING ‚Äî ultrasn0w users don‚Äôt update yet! See a few paragraphs down!
The 4.3.1 untether exploit comes courtesy of Stefan Esser (@i0n1c on twitter), a security researcher based in Germany. Stefan has a long history of vulnerability research, and ironically his first contribution to the iPhone jailbreak community was improved security ‚Äî last year he beat Apple to the punch and implemented ASLR for jailbroken iPhones with his ‚Äúantid0te‚Äù framework. We‚Äôre happy to see that Stefan then turned his iPhone attention over to an untethered jailbreak exploit!
The 4.3.1 untether works on all devices that actually support 4.3.1 except for the iPad2:
iPod touch 3G
iPod touch 4G
AppleTV 2G (PwnageTool only for now)
The reason the untether won‚Äôt work as-is on the iPad2 is that it requires a bootrom or iBoot-level exploit to install, and the iPad2 is not susceptible to either the limera1n or SHAtter bootrom exploits.
WARNING WARNING ‚Äî ultrasn0w users don‚Äôt update yet! We need to first release an update to ultrasn0w that fixes some incompatibilities when FW 4.3.1 is used on the older basebands supported by ultrasn0w. And remember once we do fix ultrasn0w for 4.3.1 (we‚Äôll announce it here and on twitter), you must only get there via a custom IPSW from PwnageTool, Sn0wbreeze or xpwn! Don‚Äôt ever try to restore or update to a stock IPSW, or you‚Äôll lose the unlock!
For everyone else, redsn0w is the easier program to use (and redsn0w runs on both Mac and Windows). Please check out places like iClarified for some excellent guides on how to use both PwnageTool and redsn0w.
Feel free to ask for help in our comments section. Thanks once again to our fantastic moderators for volunteering their time and knowledge and keeping order: Confucious, sherif_hashim, dhlizard, Frank55, and subarurider!
