Apple is set to unveil its first folding iPhone, anticipated to cost more than $2,000, at its annual product event on Wednesday. This launch represents the biggest design change for the iPhone in nearly two decades and is seen as a crucial test for new CEO John Ternus, who will also need to demonstrate Apple's advancements in AI with its Siri virtual assistant. The foldable phone is expected to feature sturdier hinges and reduced screen creasing.

The introduction of a folding iPhone is a response to increasing competition in the smartphone market, with other manufacturers like Samsung and Huawei already having foldable devices. Analyst firm IDC predicts the foldable phone market will generate over $45 billion in revenue by the end of 2027, indicating a growing demand that Apple aims to capture.

While the folding iPhone takes center stage, Apple may delay refreshes for its Air products and lower-end iPhones until the spring. This strategic timing could allow the company to focus its initial marketing efforts on the high-profile foldable device and gather feedback before updating other segments of its product line.
