I dont get it. Why the FBI doesnt give the iPhone to Apple. Apple installs the Cracking-iOS; creates a backup and restores this to a new iPhone and gives it back to the FBI. Then Apple vaporizes the original iPhone & software.
So the FBI never gets the "golden Key" but a backup from the original iPhone.
Case closed.
IANAL.<p>1) Probably the FBI has too keep a close control of all the steps to make the evidence admissible in court. If not, how would be the judge sure an evil Apple employed has not made up the evidence?<p>2) If Apple can unlock this phone, the next day it would receive a full truck with phones from other FBI cases. And the next month a container with phones from other countries that are also fighting terrorism, like China or Russia or whatever country you prefer ...
Because the issue isn't the FBI having the software, but rather the government being able to compel Apple to do this in the future with any phone for any reason.
