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.
In November pod2g warned iPhone owners not to update to iOS 5.0.1 if they planned to jailbreak their phones. An important exploit was closed by Apple after a "security flaw" was publicized by security expert Charlie Miller. The details about pod2g's current jailbreak are still a bit dodgy, so I would advise avoiding iOS 5.0.1 for now. The security flaw is not a huge risk and will be patched by developers through Cydia if the jailbreak is released to the public.
The Chronic Dev Team recently announced that they have collected over 10 million crash reports submitted by iPhone owners. This is also another positive sign that an untethered jailbreak is near.
