Your original claim was that ALL iPhones are sold unlocked. You now claim he says he says, according to you "Yup, got a couple iPhone 6s & 6 pluss; a couple ATT, and a couple T-Mobile." Why would he bother to buy the AT&T phones when the unlocked T-Mobiles would take an AT&T sim just fine? Why would he do that? Again, dinodino, it doesn't make sense and I refer you again to Judge Judy's admonition. That would require that AT&T unlock the iPhone for use on a non-AT&T network. None of this had you mentioned before. . . which I think you would have commented he had bought several. Your omission of those claims are as revealing as your original statement. Then you have him going into an irrelevant mini-tutorial about AT&T with GSM and Verizon's non-world standard CDMA. This just doesn't ring true.
I spent a year as the foreman of my county's Criminal Grand Jury, listenening to dissembling and people trying to make things sound reasonable. . . adding things to their narratives to add verisimilitude. I got very good at detecting BS. Frankly, I see you're dancing like that.
As I told you, Apple's in store and online policy (as per Apple) was intended for specifically blocking straw sales that seemed to be purchasing for export resale. Buying multiple phones met that criteria because that is what it would appear your friend's purchase would appear to be. . . especially when purchased for two different platforms. Perhaps I'm wrong. . . but I don't think so. . . given the absolutist position where you started in this conversation, and your changing story.
I'm done.
I mean this in the best possible sense: you and your imaginary grand jury can collectively suck a bag of dicks. Shall I call you from JED on one of the phones in question to wish you the same?
