Apple's iPhone 4S has smashed records by selling more than 4 million devices in three days – more than double the 1.7 million sold during the launch of its previous model.
Customers lined up outside stores from Tokyo to Sydney and Frankfurt in order to get their hands on the new iPhone, with Apple co-founder Steve Wozniak among the first to buy a handset.
The 4S went on sale on October 14 in the US, Australia, Canada, France, Germany, Japan and the UK.
It will debut in 22 more countries on October 28, and a further 70 by the end of 2011.
But Samsung – which recently surpassed Apple in global smartphone sales for the third quarter – is suing Apple to stop sales of the iPhone 4S in Australia.
No release date or pricing has been announced for the iPhone 4S in New Zealand yet.
