People have been dreaming about video calling for decades. iPhone 4 makes it a reality. With the tap of a button, 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, iPad 2, the new iPod touch, or Mac over Wi-Fi. No other phone makes staying in touch this much fun.

Thanks to the Retina display, everything you see and do on iPhone 4 looks amazing. That’s because the Retina display’s pixel density is so high, your eye is unable to distinguish individual pixels. Which means Text in books, web pages, and email is crisp at any size. Images in games, movies, and photos pop off the screen. And everything is sharper.

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.* This smarter approach to multitasking is available only in iOS 4.
