Apple blocks iPhone jailbreaking with modified boot ROM
Anyone looking to buy an iPhone for jailbreaking may be out of luck until a new exploit can be found. iClarified and many other sites are reporting that new (shipping since last week) iPhones have an updated Boot ROM that is no longer vulnerable to the 24kpwn exploit used to jailbreak the 3GS.
Macrumors speculates that the block on jailbreaking may be linked to software piracy on jailbroken iPhones. While there are genuine reasons for jailbreaking and unlocking, the continued piracy of cheap apps isn’t going to help the cause. Ripping off apps that cost only a few dollars/pounds is just hurting the developers that make the iPhone such a great platform.
