First day in stores
Apple's first foldable phone, the iPhone Duo, went on sale at Apple Store locations worldwide on Friday, October 23. The company announced the rollout in a brief statement.
Why it matters
iPhone Duo marks Apple's first entry into the foldable-screen phone category, positioning the company against rivals already selling foldables.
The app side
Apple had said apps optimized for the device would be ready the same day. A foldable screen requires apps to adapt to different display sizes.
Limited detail
Apple's announcement did not include pricing, a country list or technical specifications. Those details should be tracked through the company's product pages and store announcements.
