Yeah, basically it means that the chain of trust is (without a computer) broken all the way down in userland (booted iOS), and limera1n only acts as an injection vector for something that gets loaded on iOS boot to modify the loaded kernel in memory and allow unsigned code execution. An untethered bootrom exploit is one that ignores the signature on the LLB (such as Pwnage 2.0 or 24kpwn) allowing us to upload a modified LLB and iBoot (such as one that loads a jailbroken kernel, or in our case, OpeniBoot).

So you're basically saying that SHAtter and geohot's exploit can't boot OpeniBoot? I thought we needed a bootrom exploit for OpeniBoot...

We should be able to run OpeniBoot in a tethered form. However you won't be able to have it permanently installed and dual booting.

yeah but we can have android on our iPhone 4's, even if it requires a computer to boot it would still be awesome. Imagine how fast it would run, even without optimization..
