- jevinskie 11y agoEvery single version of the iOS kernel has been dumped. That gives you most [0] of what you need to craft a modified version. The largest barrier to running these modified versions is getting the target hardware to accept them as authentic. All public bootrom/iBoot exploits on the iPhone 3GS/4 patch the bootloaders' RSA authentication out in some form or another. There are no public bootrom exploits out for iPhone 4S+ devices. Thus, having the signing key (or the power to compel signing at will) is an incredible ability privy only to Apple. [0] Some Mach-O information is lost. Decryption of the imgX formatted kernel is preferable.
