I-phone While everyone else was busy trying to keep up with iPhone
While everyone else was busy trying to keep up with iPhone, we were 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.Facetime
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 straight out of the box. No other phone makes staying in touch this much fun.
Two cameras two views
iPhone 4 has two cameras: One on the front, which focuses on you. And one on the back, which focuses on everything else. FaceTime lets you switch back and forth between them at any time during a video call. All you have to do is tap a button.
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
Mulittasking
iPhone 4 introduces a whole new way of multitasking. Now you can run your favourite 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.
Recording and editing
Shoot your own films 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 now available on the App Store.
