So, basically, go ahead and do crimes like this if you don't mind 5 years in jail when you can split a few million dollars in profit afterward. (Or a bit less since they likely sold them cheaper than Apple did. But even at 3/4 or half the price, that's a lot of money for 6000 iPhones.) Kind of the American corporate motto: a million dollars in fines for criminal acts is okay when you made 5 million in profit by it.
Apple would have known exactly what phones were sent out in this scheme, at least most of them. Wouldn't they be able to remotely disable them, justified under "receiving stolen property" laws? Or have service providers block them based on IMEI?
