Untethered Jailbreak
iPhone 5 Jailbreak Update: Comex Leaves Apple, Untethered Jailbreak Getting Closer
JailBreakMe developer Comex (aka Nicholas Allegra) has parted ways with Apple after interning for the company for over a year. Comex tweeted the news on Friday: "So… no point in delaying. As of last week, after about a year, I’m no longer associated with Apple."

When asked why, Comex responded that he forgot to re-up with Apple by failing to reply to an email. Allegra also told Andy Greenberg of Forbes he does not plan to return to the jaibreaking community, and that his split from Apple did not end badly:
"When I asked Allegra what he plans to work on now, he said he’ll focus on his work at Brown, and doesn’t foresee working on new jailbreaking tools for iOS any time soon."
iOS 5.1.1 Untethered Jailbreak 'Info Sheet'
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.
iPhone 4S Jailbreak Absinthe Gets Update (Mac OS X)
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.
How to Jailbreak iPhone 4S With Absinthe (Windows) iOS 5 / iOS 5.0.1
The Absinthe jailbreak tool for Windows is here. Chronic Dev Team released a new version of Absinthe that not only corrects some early bugs in the process, but will bring the full iPhone 4S and iPad 2 jailbreak to Windows users. The solution comes from pod2g and a "dream team" of iOS hackers working around the clock.

Absinthe is fully untethered and can be installed on mobile devices running Apple's latest firmware (iOS 5.0.1). Development efforts continue despite the successful release of Absinthe, with the iPhone Dev-Team working on new tools including an updated redsn0w coming soon.
iPhone 4S Jailbreak Instructions (iOS 5 / 5.01 Absinthe Untethered)
UPDATE: Instructions for using Absinthe for Windows are here.
Great news has arrived for iPhone 4S and iPad 2 owners looking to jailbreak. Chronic Dev Team released the highly anticipated Absinthe jailbreak tool for Apple A5 devices running iOS 5 and iOS 5.0.1 firmware. This solution was in the works for some time, thanks to the efforts of developer pod2g and a "dream team" of iOS hackers.

Like the most recent iPhone 4 jailbreak, Absinthe is untethered and can be installed on mobile devices running Apple's latest firmware (iOS 5.0.1). The greenpois0n servers delivering Absinthe were down for hours today thanks to heavy traffic from jailbreakers across the globe.
iPhone 4S Untethered Jailbreak Only a Few Days Away [Video]
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.
Untether Your iOS 5.0.1 Jailbreak With Corona
Chronic Dev Team has released a jailbreak tool on the Cydia app store for those who have already installed a tethered jailbreak on their iOS 5.0.1 devices. Using this tool, called Corona 5.0.1 Untether will modify your iPhone with the same exploits used in redsn0w. Unlike the redsn0w jailbreak process, Corona requires no computer to untether a jailbroken device.

In order to successfully install Corona, your iOS device must already have a tethered jailbreak installed along with iOS 5.0.1. Do not use Corona if you're using a hybrid iOS 5.0/5.0.1 jailbreak! This requires installing and running redsn0w after a clean restore to stock iOS 5.0.1.
Dev-Team Releases iOS 5.0.1 Untethered Jailbreak (A4)
Thanks to the hard work of pod2g the untethered iOS 5.0.1 jailbreak is finally here. He shared his exploits with the iPhone Dev-Team and Chronic Dev Team, and now there's a suite of tools for anyone running iOS 5.0.1 on a non-A5 device. This is great news for jailbreakers, however it also means that iPhone 4S and iPad 2 owners are still waiting for an untethered jailbreak.

First off, the redsn0w jailbreak tool has been updated to 0.9.10b1 on OS X and Windows. This new version of redsn0w requires iOS 5.0.1 installed on your device, and will jailbreak the iPhone 3GS, iPhone 4 (GSM), iPhone 4 (CDMA), original iPad, iPod touch 3G and iPod touch 4G untethered.
New Video Shows Untethered Jailbreak is Right Around the Corner
iPhone hacker pod2g released a video showing off his new iOS 5.0.1 untethered jailbreak working on an iPhone 4. The new untethered jailbreak should be "ready for prime time" in a few days according to his blog. The exploit does not work for the iPhone 4S or iPad 2, but it will work with other iOS devices. Pod2g previously uploaded a video to YouTube showing the exploit working with an iPod touch, and it has been tested on an iPhone 3GS and iPad.
The video shows the jailbreak working after the iPhone 4 has been switched off and on proving that it's untethered. It uses the same code patches as redsn0w, so it should feature the same level of stability. Earlier this week pod2g posted two updates on his A5 jailbreaking progress.
