I currently have TMo on an unlocked iPhone. Knowing that you can't order an iPhone X sim-free on Oct 27, I'm thinking of getting a VZW line around Oct 24 just in time for pre-order so I can get a Qualcomm modem chipped phone and then order a VZW iPhone X. After a few days, I plan on cancelling the line within the 14 day grace period provided by VZW. Think that'll work?
