I know it's fun to mock FBI/courts/Congress for not understanding the encryption with this iPhone thing, but… honestly I don't get it either

Today I read a blog post about why Apple technically can't do it, and another about why they can. Both seemed equally convincing/confusing.

they can absolutely do it, but it would require creating a hostile OS update and signing it with their privileged key

on 6-and-up devices too? I definitely read an article that said "nope" (also, I still don't get what that "key" is)

on 6-and-up the enclave enforces timing, but its software can be updated too if you can prove you’re apple (that’s what the key does)

it's possible that the timing rules are implemented in a way which cannot be updated (white paper doesn't say), but unlikely

Thanks! This is helping. Next q: can you force a locked iPhone to update its OS?

yes, if you're apple (ie. have their crypto keys). sometimes people finds a hole in this (jailbreak). none publicly known in enclave.
