Fortunately, B&H now lists the V30S ThinQ at $729.99, thus taking $200 off its original price. The handset - already available in South Korea - still doesn't have a proper release date for the US, but it'll likely start shipping soon. In any case, this is the official US variant of the LG V30S, so you'll be able to use it on all relevant carriers, including Verizon, AT&T, T-Mobile, Sprint, or US Cellular.
B&H is offering the LG V30S ThinQ in two color versions (Glossy Moroccan Blue and Matte Moroccan Blue), and both seem to be exclusive to the retailer. If you're interested, you can find both colors at the source link below.
