Sony Xperia XZ Premium officially released in the US6
As you can see following the source links below, right now, only the black and chrome (silver) versions of the Xperia XZ Premium are in stock at Amazon and Best Buy. Both retailers say they will have a pink model in stock starting July 3.
The Xperia XZ Premium is a water-resistant, Android Nougat-based device that offers pretty much everything a 2017 high-end smartphone should offer, except for a fingerprint scanner, which is disabled on the US model. We won't bore you by relisting the specs of the phone, but we advise you to check out our Xperia XZ Premium review to see what we liked (and didn't like) about it.
Before thinking of buying the Sony Xperia XZ Premium in the US, do note that the phone only works on GSM/LTE carriers like AT&T and T-Mobile, so it can't be used on Verizon, Sprint, or US Cellular.
