I pre-ordered a 6s Plus from verizon wireless. At the same time, I also made a reservation at the Apple Store to do their upgrade program. If I do end up going the Apple Store route, I still have this 6s coming from Verizon Wireless. I know I can just return the unopened box to Verizon but my question is can I sell that unopened phone from Verizon without activating it? I'm reading about possible supply constraints for the 6s Plus but who knows. I did pay full price for the phone from Verizon and therefore don't have any contract requirements tied to it.
