Hopefully this is the right part of the forum for this... So I pre-ordered a jet black 128GB iPhone 7 this past Friday. I'm a T-Mobile customer but I wanted to get an unlocked-paid in full Verizon/Sprint/CDMA version as the T-Mobile/AT&T is GSM only. Since I'm not a Verizon or Sprint customer, I couldn't get an account verification and ultimately just settled for the unlocked T-Mobile version. Thing is, my phone won't ship out for 2-3 weeks and has a target delivery of October 4-10. Between now and then, I'd like to see if I can get a Verizon/Sprint version if I can in store then cancel my order. So my question is, what are the chances that I'll be able to get an unlocked Verizon/Sprint jet black iPhone 7 in store before mine ships? Further, if I go to the Apple Store, will they sell it to me without an account verification as I plan to stay with T-Mobile?
