Apple has sold more than 700 million iPhones since the device launched in 2007. CEO Tim Cook made the announcement at Apple's Spring Forward event last night, which also saw the Apple Watch unveiled.
"Recently we sold our 700 millionth iPhone," Cook said. He went on to say sales were going from strength to strength.
"iPhone is growing stronger than ever and if you look at last quarter we sold at a rate of double the rest of the industry.
"This led the iPhone to be the top selling smartphone in the world."
The two latest instalments in the series, the iPhone 6 and 6 Plus, sold 10 million on their opening weekend alone.
By contrast, the Samsung Galaxy S4 sold around 20 million units in its first two months on sale.
Cook also claimed the iPhone has a customer satisfaction score of 99 per cent. "These numbers are unheard of," he added.
Apple is rumoured to be readying its next handset, the iPhone 6S, for release in September. Like other S iterations, it's thought to be a minor refresh rather than a radical overhaul.
Last night, Apple gave us more details on the Apple Watch.
The device has a battery life of 18 hours, and will sell for £299 when it hits the shelves on April 24th. Pre-orders start on April 10th – that's the same day the Samsung Galaxy S6 goes on sale. Coincidence? We think not.
