Only yesterday we reported that well known iPhone hacker Pod2g has released a new video in which he shows a working solution to jailbreak 5.0.1 untethered on iPhone, iPad and iPod touch. Now he has started a new blog in which he will be posting future updates regarding this jailbreak.
At first Pod2g only released the video and confirmed that when he finally makes the exploit available to public, it will be possible to jailbreak 5.0 untethered on iPhone, iPad and iPod touch. There's also a possibility that this jailbreak will be compatible with iPhone 4S and iPad 2 as well. Later that day he confirmed via Twitter that there was a big chance that users will be able to jailbreak 5.0.1 untethered as well once this exploit has been released.
Now he has started a new blog in which he will be posting regular updates regarding this exploit. As of now, no one knows when its going to be released to the public. Pod2g isn't revealing much in his statements, mainly because he doesn't want Apple to get the chance to patch this exploit before people get the chance to jailbreak 5.0 and 5.0.1 untethered. However, he has confirmed that the exploit used for this jailbreak is a userland one. Pod2g, in his first blogpost wrote:
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.
The main difference between a userland exploit and a bootrom exploit is that the former is software based, meaning all that Apple needs to do in order to patch it is to release a new software update. The bootrom exploit requires hardware change, which obviously Apple can't do once it has started shipping the iOS devices.
Things look promising about the ability to jailbreak 5.0.1 untethered as well as 5.0 firmware on iPhone, iPad and iPod touch. You can follow up with Pod2g by visiting his blog. We'll keep you regularly updated on the status of untethered jailbreak for iOS 5.
