Let me tell you this, there's a GREAT reason geohot is burning this exploit. Here's why: The vulnerability for limera1n, doesn't exist in the newer devices iBoot.. What does this mean? The vulnerability doesn't exist in the bootrom either. Why? iBoot and bootrom are the same. He checked to see if he can exploit it in the newer devices, he couldn't. That's why he wishes to release the tool now and save SHAtter.. Reasonable right? Thought so.
