iPhone 5 has sold over 5 million units since it was released last Friday.
"Demand for iPhone 5 has been incredible and we are working hard to get an iPhone 5 into the hands of every customer who wants one as quickly as possible," said Apple CEO Tim Cook.
"While we have sold out of our initial supply," he added, "stores continue to receive iPhone 5 shipments regularly and customers can continue to order online and receive an estimated delivery date. We appreciate everyone?s patience and are working hard to build enough iPhone 5s for everyone."
In addition to the above it's also been announced that 100 million devices now have iOS 6, since it was released last week. That's a whole lot of downloading.
