have to buy the phone directly from the carrier, unfortunately.

My mother bought a 128gb 6s from AT&T (and I was with her), and when they gave it to her the box was open and it was covered with greasy fingerprints. She hesitantly accepted it, but there was something very wrong with that phone, and they refused to replace it with a new non-defective one without charging her a "restocking fee," even though she told them that was illegal, and eventually even went beck to the store with a printout of the law prohibiting the practice. They were just horrible to her. And should they really be "restocking" a defective phone anyway? Eventually she was able to get the Apple store to replace it for her, and her new one is great, but I would definitely go well out of my way to never buy a phone directly from AT&T after that experience.

I agree.  Restocking means you are returning a product not replacing a defective product with a good one.  This shows the store employee is inept.  

individual device, this could then be split in two,  Apple could hold one half of the key and the other half could be held by FBI/Government/other agency. The two halves of the key could only bought together with a court order and the physical presence of the device.  Even if both halves of the keys were stolen it would be useless with out the actual physical device.
