This whole thing will be bad for Apple if it is found you can unlock an iPhone anyways, once again. While I applaud Apple for not caving in to the FBI and offering them a hack tool or backdoor, the fact that an independent party found a way into the phone anyways is pretty bad for Apple.
Apple is too rich a company and has too many people and resources for them to continuously release phones and iOS with security exploits. Apple makes their own hardware, they make their own software, they distribute their own products; why can't this company make their hardware the most secure devices on the planet? Q/A and Security should be Apple's top priorities, not removing headphone jacks and making their phones thinner. If Apple wants to be the champion of people's rights, security and privacy then invest all them billions in obscene profit margins back into the quality of their products, not building grandiose UFO looking headquarters.
While I am sure that momentous effort is going to unlocking this one particular phone and it's not an exploit for the casual hacker, just go on YouTube and see ALL the videos over the years of how people have bypassed the lock screen on the iPhone simply by accessing the camera or panel or something else and poking around a little.
Apple can't be a poser and fight for the people while their products continue to be hackable anyways.
