By making a registration message voiding any warranty, what incentive is there above jailbreaking?

At least with a jailbroken iPhone, you can virginize it and fall back under warranty (so long as it's not bricked).

I think I understand what you're getting at, but it seems that this option involves making it as difficult as possible to hit a toggle switch which in turn makes it easy to unlock an iPhone.

The main reason why I think Apple would never go this route is that this allows for a customer experience that they don't want to happen. If you go out of your way to brick your iPhone and void your warranty, that's your own business, but supporting that as an option just doesn't seem to make much sense.

But where does it end? I can imagine tons of cool kids trying to be just like you, only they don't know what they're doing and you have customers with bricked iPhones complaining to Apple. How would the cost structure work? There are bound to be people rioting if an unwalled iPhone were to cost $400 instead of $300. I'm an admitted Apple apologist, but we have to think about feasibility here. If you really wanted a "more open" iPhone, there's already the possibility of rooting it. You get the features you want and you deal with the same risk of Tetris-ing as an official Apple sanctioned unwalled iPhone.

In order for this to be of use to law enforcement, uniqueness is not necessary. As long as there are few enough people that share identical fingerprints, some information would be better than no information (you would still run into problems with identical twins if it is the case that they share the same fingerprint.)

I'm not entirely sure that nuclear power generation will reduce imports from the Middle East, primarily because nuclear power doesn't replace the oil we use with regards to our current energy consumption habits. On the other hand, you are right that it is power that is generated more "greenly" than burning coal and hopefully with the advent of nuclear power we will see, as you say, electric vehicles that really are green.

Don't live free and don't die? Well, that sounds fun.
