Motorola recently began accepting preorders for the Nexus 6 on its U.S. web site.
Both the white and blue models are available in 32GB and 64GB variants for $649 and $699, respectively. Motorola is selling the unlocked GSM model at the moment. Google is also selling the Nexus 6, though its supply is currently exhausted.
The Nexus 6 will be made available from wireless network operators, including AT&T, Sprint, and T-Mobile, later this month. Shipping times have yet to be announced.
