Apple has unveiled its first foldable iPhone, the Duo, under new Chief Executive John Ternus, marking a significant shift in the product's design nearly 20 years after its debut.

• The Duo starts at $1,999 in the US and £1,999 in the UK, making it the most expensive iPhone to date.
• Chief Executive John Ternus, who recently took the helm, presented the device, emphasizing its innovative design inspired by the iPad.
• This move addresses past criticisms of a lack of major product innovation from Apple, though analysts caution about its potential market reception compared to existing foldables which comprise only 2% of smartphone sales.
