Please be patient, back to this because I am trying to understand.
Unless NAND memory duplication is something new, the "hack" sounds like something that should have been figured out ages ago.
Does this make more sense:
..I'd be willing to lay odds that this involved copying the data and replicating it many times over, then "tricking" the iPhone into thinking the replicated data is the original data. Basically, an assembly line process. Bump the number up to, say, an 8 digit code, and the cost of this approach starts to become excessive.
Is this a viable solution?
Apple will move the delay between passcode attempts from iOS into the secure enclave of the chip.
I wonder if tacit believes the phone was hacked... For whatever reason, this story intrigues me.
