Apple has unveiled its first folding smartphone, the iPhone Duo, in India. This new device starts at an unprecedented Rs 2,99,900, significantly raising mobile phone prices. The iPhone Duo features a 7.6-inch inner display and a 5.4-inch outer panel for versatile use. Alongside the Duo, the iPhone 18 Pro and Pro Max models also see premium pricing adjustments. These price hikes reflect industry-wide increases driven by rising memory chip costs.
