Starting with version 0.9.12b2, redsn0w will now explicitly ask users with limera1n-able devices whether they want to inject rocky-racoon using the DFU ramdisk method or the backup/restore method (the ramdisk method is better for those with lots of media on their device that would create very large backups, and it’s required for those with unactivated iPhones). If you’ll always want to use limera1n, you can select that in the Preferences pane. It also fixes an iBooks issue on old-bootrom 3GS iPhones, and provides more useful error messages when things go wrong.
RedSn0w 0.9.12b2 supports untethered iOS 5.1.1 jailbreak for all devices:
redsn0w allows owners of A4+earlier devices to install rocky-racoon two different ways:
backup/restore method similar to Absinthe and cinject
its traditional limera1n-based ramdisk install. If you have a lot of media on your A4 device (music, movies, TV shows, etc), then the ramdisk method is preferrred because it avoids any possibility of later problems related to syncing to iCloud (including Photo Stream and Music Match). The ramdisk method is not available for A5 devices or later because limera1n can’t be used. If you’d like to use redsn0w’s ramdisk method, just be sure to put the A4 device in DFU or Recovery mode before starting redsn0w (otherwise it will immediately start to use the backup/restore method).
We’ve also added a new redsn0w feature specifically for those who got in on the SAM unlock: you can now include your SAM tickets as part of your initial ramdisk jailbreak of iPhone4 or earlier, or alternatively you can upload your SAM tickets to any device after its been jailbroken. redsn0w accepts either the individual SAM activation ticket plist file, or the entire zip file created by redsn0w’s “Backup” button. As usual, redsn0w continues to cover all of its previous jailbreaks and untethers (so redsn0w-0.9.12b1 covers everything from 5.1.1 all the way back to 4.1).
PwnageTool also avoids any possible sync issues, but again it applies only to A4+earlier devices. If you unlock your iPhone with ultrasn0w or a commercial method, you must use PwnageTool to avoid updating your baseband otherwise you’ll lose the unlock. PwnageTool will also jailbreak+untether the AppleTV2,1 5.0_2B206f (unless you customize the IPSW further, you’ll have just basic SSH access to the device).
Just like version 2.9.4 the new 2.9.5 version supports untethered jailbreak of A4 devices on iOS 5.1.1. Sn0wbreeze can be used to create a custom firmware with jailbreak and preserve iPhone modem (baseband) version for unlock.
Sn0wbreeze 2.9.5 supports iPhone 3GS, iPhone 4, iPad 1, iPod Touch 3G, iPod Touch 4G and Apple TV 2G. It does not work with A5 devices, like iPad 2, iPad 3 and iPhone 4S.
Pod2g has announced via Twitter that he successfully made untethered jailbreak of the iPhone 4 on iOS 5.1. Previously, three parties had demonstrated the jailbreak of iOS 5.1: I0n1c, the iPhone Dev-Team, and Chpwn/Phoenixdev. Only I0n1c claimed untethered jailbreak, but made it clear that he will not be releasing his jailbreak to the public.
Thankfully pod2g has announced that he’s also succeeded in untethering the jailbreak.
Heya! My iPhone 4 running iOS 5.1 is now untethered
Obviously, this is an important step towards public release of the iOS 5.1 jailbreak. This past Monday pod2g revealed the discovery of 2 big vulnerabilities. 1 kernel land and 1 root land. It appears that progress is being made!
Pod2g has announced the discovery of 2 new vulnerabilities in his quest to jailbreak the iPhone.
News: a productive week-end. Found 2 big vulnerabilities. 1 kernel land and 1 root land.
Too bad I have to be secret again…
Last week pod2g noted that a jailbreak of iOS 5.1 would take at least a month to complete. We’ll post more information about how these new vulnerabilities will affect that schedule as soon as we hear more.
If the kernel land vulnerability is exploitable this could provide a jailbreak for the device no matter the firmware.
