Opening sales outstrip the iPhone 4S by one million.
Apple has sold five million iPhone 5 handsets in three days, following sales beginning on Friday, September 21st.
That outshines the efforts of the iPhone 4S, which hit four million in its debut weekend last October.
Of course, demand was already through the roof with iPhone 5 pre-orders passing two million in 24 hours – more than doubling and tripling the respective efforts of the iPhone 4S and iPhone 4 – though many buyers aren't likely to receive their orders until next month.
The 5 is available in the US, the UK, Australia, Canada, Germany, Hong Kong, Japan and Singapore at launch, but will land in 22 more countries on September 28th.
The goal is to reach more than 100 countries by the close of 2012, which will likely add to sales surge ahead of Christmas.
Tim Cook, Apple’s CEO, said: "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.
"While we have sold out of our initial supply, 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 other iPhone-related news, one O2 worker was so keen to get his hands on a device that he stole 252 handsets from his store.
