First batch of iPhones XR already sold out
The iPhone XR was released for pre-order a few days ago, and almost immediately some color options were sold out, specifically red, coral and yellow. Rest color had a somewhat slower start, but only four days later they are also sold out.
Shipment dates through different national Apple stores have all been pushed back by 1-2 week, specifically in the USA, the UK, Canada, Japan, Germany, France and China. Experts estimate that so fat Apple has sold around 12 million XR devices, and another estimate says that this will be the best selling smartphone of 2018.
