While everyone else was busy trying to keep up with iPhone, Mac was busy creating amazing new features that make iPhone more powerful, easier to use, and more indispensable than ever. The result is iPhone 4. The biggest thing to happen to iPhone since iPhone. Face Time: People have been dreaming about video calling for decades. iPhone 4 makes it a reality. With just a tap, you can wave hello to your kids, share a smile from across the globe, or watch your best friend laugh at your stories — iPhone 4 to iPhone 4 over Wi-Fi. And it works right out of the box. No other phone makes staying in touch this much fun. Retina Display: The Retina display on iPhone 4 is the sharpest, most vibrant, highest-resolution phone screen ever, with four times the pixel count of previous iPhone models. In fact, the pixel density is so high that the human eye is unable to distinguish individual pixels. Which makes text amazingly crisp and images stunningly sharp. Multi-Tasking: iPhone 4 introduces a whole new way of multitasking. Now you can run your favorite third-party apps — and switch between them instantly — without slowing down the performance of the foreground app or draining the battery unnecessarily.1 This smarter approach to multitasking is available only on iPhone. HD Video Recording: Shoot your own movies in high definition. Capture impressive video even in low-light settings, thanks to the advanced backside illumination sensor and built-in LED light. Then edit and create your own mini-masterpiece right on iPhone 4 using the new iMovie app — with Apple-designed themes, titles, and transitions. It’s coming soon to the App Store for $4.99. 5-Megapixel Camera with LED Falsh: Take beautiful, detailed photos with the new 5-megapixel camera with built-in LED flash. The advanced backside illumination sensor captures great pictures even in low light. And the new front-facing camera makes it easy to take self-portraits.
