Untethered Jailbreak

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.

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.

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.

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.
