they already found an exploit, GG
You are correct
Taken From iOS 4.1 jailbreak exploit found just hours after release
As we reported yesterday evening, iOS 4.1 was released with a number of new features, along with security and bug fixes.
But within hours of it going live, hackers had managed to find a method which can be used to jailbreak devices running the latest version of Apples operating system.
The Register reports that pod2g, a member of the iPhone Dev-Team, has uncovered an exploit in the boot Rom of iOS devices. Because this is such a low-level hole in the system, it wont be a case of Apple being able to simply patch it up, either.
Apple will have to make hardware changes and tweak the boot Roms on its iGadgets to successfully close up this particular exploit.
Having said that, theres still a considerable amount of work to do before a functioning jailbreak is ready to roll, by all accounts. But were betting it wont be too long, and the problem this time round will be much more of a headache for Apple than the previous jailbreak.
Although there could be a potentially very simple solution. Just let people run what they want on their iPhones (like thats going to happen)
