While we can’t say for sure, it has been noticed that pre-orders for the phone are currently being accepted by B&H Photo, which is expected to open come 2nd of October. B&H’s listing does not state when the phone will begin shipping, but pre-orders will begin next week, which means that a release shouldn’t be too far behind.
It is possible that the 21st of October date will still hold true, but we’re hoping that the early pre-orders means a shorter waiting time. There is no word on how much the unlocked phone will be priced as B&H did not state its pricing. In any case we guess for now it appears that B&H is one of the few (or possibly the only) retailer in the US to accept pre-orders for the handset.
However if you recall, a week ago T-Mobile teased that the LG V20 would be coming soon, so at the very least we know that T-Mobile will be carrying the phone as well.
