From what I'm seeing Apple will not sell me an AT&T iPhone without being an AT&T customer. Is that correct? In the past I've been able to just buy the T-Mobile model and put my AT&T (or AT&T MVNO) SIM in it but this year I want to get the actual AT&T model because it has the extra LTE band 30. It seems like this isn't something they allow though. It seems kind of strange that I am wiling to pay full price for the phone but they won't sell it to me unless I either provide a current AT&T account or sign up for a new one. My issue is I just switched to Cricket last week and am using the Cricket SIM in my locked AT&T iPhone 6 right now with no problem, but if I had known I needed an AT&T account to buy the AT&T iPhone 6S I would have just waited a week before porting my number away from AT&T... seems kind of ridiculous that if I kept my AT&T account I could have bought the phone and then immediately canceled the AT&T account but since I did that a week ago I now can't buy the AT&T phone.
