But this was always likely to be high as even though sales of the 4S were high, as it was visually the same handset as the 4, fewer people would have gone out of their way to upgrade, buying out early etc. So this year there should have been a load of first time buyers, and a bumper crop of freshly available 2-year upgraders.
And on cue, Apple has confirmed that, following on from the 2 million pre-orders taken in the first weekend, it has sold over 5 million iPhone5 units in the first 3 days of availability.
Apple’s CEO Tim Cook 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.
