You're incorrect and have fully misunderstood what the FTC is saying (not that I'm surprised, since you obviously wouldn't need to look this up if you were a T14 law student or anything). What that page refers to are scams carried out in an attempt to corner an unwilling buyer into paying for an item they did not request.
Apple isn't trying to scam the original poster, but rather made a logistical error. Please refer to the following quotation from the page, which is the only thing that even remotely pertains to the situation described in this topic:
Now, I know you're probably going to try and act as if I'm the incorrect party, but I ask that you attempt to utilize rational cognition in regards to the issue at hand. If every previous "consumer protection" Q&A on that page referred to situations similar to the one our original poster has experienced, then there would be absolutely no need to provide any explanation for "honest mistakes." Apple did not mean to send him this phone, and only did so as a result of another contract the original poster made with Apple. If Apple contacts you and requests that you return the phone, as they undoubtedly will if they realize their error, the original poster would absolutely lose a court case should he fail to adhere to their requests and then attempt to contest the $700 charge.
Do the right (and, you know, legal) thing and contact Apple, notify them of their error, and hope for a $100 headset in return.
