About five hours ago, UPS delivered the Motorola-made Google Nexus 6. I ordered online yesterday afternoon from T-Mobile, for expedited delivery, expecting two-day shipping but getting one (under-promise, over-deliver is good customer service). T-Mo only sells the Midnight Blue model, and I chose 64GB capacity.
I could order from the carrier because we still have one line there, on a low-cost plan, which won’t change. The clarification is important because I popped in my Verizon SIM. It is my understanding that T-Mobile sells the same Nexus 6 as either Google or Motorola. Any carrier customization occurs during setup with the SIM card inserted. So far Verizon services seems to function normally.
