The iPhone Dev-Team has released an updated version of Redsn0w 0.9.6rc11 for iOS 4.3.1 untethered jailbreak. Just like Sn0wbreeze 2.5.1 for Windows, the new Redsn0w 0.9.6rc11 adds a new option to enable custom animated boot logos for iPhone, iPad and iPod touch. Official Change Log of Redsn0w 0.9.6 RC11: Those running redsn0w may have noticed we enabled too many Settings options in some versions of the jailbreak (for instance, what you want your side switch to do, even if you have no side switch because you’re not using an iPad). Release rc11 of redsn0w corrects that (you can just run it over your existing jailbreak…be sure to de-select Cydia to avoid package conflicts). Along the way, we’ve also added the option to enable boot animations…these animations can be installed via Cydia, but be sure to select which animation to use via the Settings->Bootlogo setting after you’ve downloaded an animation (and again, you can just run rc11 over your existing jailbreak…be sure to de-select Cydia to avoid package conflicts). (The boot animation we tested against was “Android Boot Logo”. It correctly installs all the dependencies needed to run the animation at each boot). Instructions for jailbreaking iOS 4.3.1 untethered using this new version of Redsn0w are exactly similar to the last release. You can follow our detailed step by step guide posted here to jailbreak iPhone 4, 3GS, iPod touch 4G / 3G, Apple TV 2G and iPad running the latest iOS 4.3.1 firmware. Those of you who are already jailbroken on iOS 4.3.1 using Redsn0w 0.9.6rc9 can simply rerun Redsn0w 0.9.6rc11 over the existing jailbreak by selecting “Allow boot animation” option as shown in the screenshot above, but make sure you uncheck “Install Cydia” option to avoid package conflict with the existing jailbreak. Ultrasn0w unlockers MUST stay away as Ultrasn0w is not compatible with iOS 4.3.1. However, the iPhone Dev team is hard at work to fix it. 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 – last year he beat Apple to the punch and implemented ASLR for jailbroken iPhones with his “antid0te” framework. We’re happy to see that Stefan then turned his iPhone attention over to an untethered jailbreak exploit! The reason the untether won’t 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 — ultrasn0w users don’t 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’ll announce it here and on twitter), you must only get there via a custom IPSW from PwnageTool, Sn0wbreeze or xpwn!  Don’t ever try to restore or update to a stock IPSW, or you’ll lose the unlock! With Redsn0w you can jailbreak your device without the need for a restore. It is simpler to use than PwnageTool. If your device is currently jailbroken with one of the previous betas, please do a fresh restore first.
