Chronic Dev Team
iPhone Dev Team member MuscleNerd has confirmed that an untethered jailbreak for iOS 5.1.1 will be released this week. Over the weekend, pod2g tweeted that "something big" was going to happen at the Hack In The Box security conference in Amsterdam being held May 21 through May 25. He later added that a public release was only a few days away. On Monday, MuscleNerd released an iOS 5.1.1 "info sheet" that revealed how the iPhone 3GS and iPod 3G made the jailbreak cut.
The upcoming jailbreak will be released via multiple tools just like the iOS 5.0.1 jailbreak was (e.g. cinject, RedSn0w, and Absinthe). All current iOS devices will be supported except for AppleTV 3. For a complete list of supported devices click here. MuscleNerd's "info sheet" is posted below.
The Dev Team has released redSn0w version 0.9.10b8b which brings only a minor bug fix. According to the Dev Team blog, the "0.9.10b8b update to redsn0w makes the zip files more compatible with the native Windows explorer (which doesn’t like leading slashes in the filenames)." The previous version released a few weeks ago helped users take advantage of the popular SAM unlock method.
In the meantime, the jailbreak community is closer to releasing an untethered jailbreak for iOS 5.1. Currently only A4 and A5 devices on iOS 5.0.1 and lower are jailbreakable. A4 devices can upgrade to iOS 5.1 but they will have to go tethered. Hopefully there is an untethered solution for all iOS devices right around the corner.
Things have been pretty quiet on the jailbreak front since the launch of the iPad 3. Today Absinthe and Corona developer pod2g broke the silence on his Twitter feed. Pod2g tweeted that he has acquired all the exploits needed to jailbreak iOS 5.1. While it's good to know that our favorite iPhone hackers are closer to a solution, fellow DevTeam member Chpwn reminded everyone that even though "all the exploits are found, this doesn't mean that a jailbreak exists," and it could be months away from a public release.
In February, iOS hacker i0n1c posted a few pictures of a jailbroken iPad 2 running iOS 5.1. The DevTeam also wrote on their blog that someone "close to the Cydia repo scene" was working on an entirely new jailbreak method.
As expected Apple has stopped signing iOS 5.0.1 with the release of iOS 5.1. If you own a jailbroken device you should not update to 5.1 because it breaks both the Corona untether and the Absinthe exploit. The Dev-Team warned both veteran and amateur jailbreakers about the dangers of upgrading on Wednesday.
iPhone 4S and iPad 2 users who did not heed the warning won't be able to downgrade back to 5.0.1 even if they did save their SHSH blobs. People with earlier devices and saved SHSH blobs can downgrade with the assistance of geohot’s limera1n exploit. There is also a tethered jailbreak for non-A5 devices if you really have the urge to get to 5.1.
I'm not sure updating to iOS 5.1 is worth losing your untethered jailbreak, but non-A5 users can sacrifice their freedom if they want to. iPhone 4S users should avoid 5.1 if they want to keep their jailbreak. However, non-iPhone 4S owners can keep their devices jailbroken by downloading redsn0w 0.9.10b6. This version is a tethered 5.1 jailbreak for non-A5 devices.
A tethered jailbreak requires that your device is plugged into a computer whenever turned on. Untethered jailbreaks offer the freedom of not using a computer every time your device reboots. Most jailbreakers prefer untethered to tethered. Since iOS 5.1 doesn't offer anything worth losing your untethered jailbreak over I would suggest avoiding it entirely. However, if you are dead set on getting to 5.1 read on for the Dev Team's warning and instructions.
Chronic Dev Team released another update to the Absinthe jailbreak tool for Mac. The new application jailbreaks the iPhone 4S and iPad 2 untethered and addresses several bugs that users reported while using Absinthe. Planetbeing reports the team has attempted to fix the white icons some users were seeing on their home screens after jailbreaking.
Absinthe version 0.2 also attempts to fix another issue where the iOS device fails to reboot after turning on VPN and touching the Absinthe icon on the home screen. Hopefully the latest version, which was also released for Windows, will help minimize problems for iPhone 4S and iPad 2 owners looking to install Cydia.
Chronic Dev Team member Dustin Howett posted a video of a jailbroken iPhone 4S on YouTube a few days ago. The video shows the A5 device running Cydia after it has been powered off and on. Howett also proves that Siri still functions by asking her to check the weather.
iPhone hacker and Corona developer pod2g republished the video on his blog saying that a release is only a few days away. It only took pod2g nine days to release his A4 untethered jailbreak after he posted a similar video of a jailbroken iPhone 4 on YouTube.
One week after the Chronic Dev and iPhone Dev Team helped pod2g release his untethered iOS 5.0.1 jailbreak for A4 devices, the iPhone hacker tweeted that the A5 version is only a week away from a public release.
Pod2g enlisted the aid of the Chronic Dev team to release his A4 exploit so he could concentrate on A5 devices. The A4 untethered jailbreak was released on December 27 while iPhone 4S and iPad 2 owners were once again left out in the cold. That is all about to change in the near future according to pod2g.
The good news is iPhone hacker pod2g is still working on his promised untethered iPhone 4S jailbreak. The bad news is he's having "processor cache" issues. Pod2g wrote on his blog:
"Here is the news of the 4S week-end.The untether fails right now because I'm having processor cache issues. I'm close, but I can't figure out what happens. It certainly has something to do with the Cortex-A9 cache management.I could sort it out quick, it's a matter of chance."
Pod2g excited the jailbreaking community when he successfully tested an untethered jailbreak on an iPod 4G and iPhone 4 running iOS 5.0.1 a few weeks ago. Currently their is no jailbreak for the iPhone 4S, but recent progress by pod2g and the Chronic Dev Team point to one being released soon. Pod2g promised another update on his progress tomorrow.
iPhone hacker pod2g just released a video showing his new untethered jailbreak for iOS 5. The video shows the new exploit working on an iPod Touch even after it has been powered down and turned back on. Pod2g tweeted that the jailbreak "will work on iOS 5.0.1" and that he plans to test it on an iPad 2 and iPhone 4S when he is ready. He also tweeted a link to his new blog which he says he'll update when he has more info.
Today I succeed in jailbreaking my iPod 3G. The exploit is user-land, rely on a user ROP payload and a kernel write anywhere exploit.
I can't give much details right now, but here are the next steps :
- upgrade the iPod 3G to iOS 5.0.1
- do the same on iPhone 4 / iOS 5.0.1
- then iPad 1 & iPod 4G
At every step, the exploit code needs certainly to be reworked, but I really don't know right now. Next, I'll return to the research for iPad 2 and iPhone 4S. I don't know if I gonna release first for other devices or not. I've to think about it. Feel free to give your opinion.
