They must have improved their supply methods.  Last year I pre-ordred a 64GB space gray iPhone 6 from US Cellular and it took about a week for me to get it.  On Friday I walked into the Verizon store at about 3PM and bought a 64GB space gray without any issues.  Two of my family members were also able to get the 16GB models.
