GeoHot was recently doing a presentation at a conference and talked all about the iPhone exploits. Be ready, he goes into some great detail about it but here’s the key phrase:
“There is also, I hinted to this a couple times, an unreleased exploit in every iPhone, iPad, and iPod touch in the bootrom to get code execution. And you know if I ever do another jailbreak, that’s the exploit I have. If you’ve seen I posted like a picture of 4.0 jailbroken. I posted my iPad jailbroken. All before Spirit was released. And I used like a completely different set of exploits which maybe when iPhone 4 comes out will be out.”
