Apple says it isn't as simple as you claim. Wake up. Don't listen to that nobody on "Trail of Bits," he doesn't know what he is talking about. That's what everyone has been telling you. Apple has now answered and they say it would take a team of between six and ten engineers, two to four weeks before they can even start testing on OTHER iPhones to make sure nothing else breaks. Plus they'd need a project lead, a document writer, and THEN a team to write the interface for the remote connection to run the brute force passcode input from a system never designed for that purpose, depending on how they intend to do that. PLUS they have to document every step of how it was done for when they are hauled into court by any potential defense attorney challenging the evidence.
YOU just assumed they would be changing the firmware.
Were they to say otherwise, it would seriously damage their public propaganda campaign. They might be telling the truth, but because they hold all the cards (meaning the source code and designs) nobody can verify that they are actually telling the truth.

I think these numbers are actually inflated over and above what it would really take. I think they are just using the regular development team, and alleging that the entire team is necessary, and I think they are also combining their "usual team" with an extraordinary abundance of caution.
I think that if they actually decide to do it, the end result will not take nearly so much time, nor nearly so many people. I think they are just playing "poor me" to the courts.
