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.

Because your iPhone goes with you everywhere,
you’re always ready to capture every moment. And with iPhone 4, you can
do it in stunning high definition. Its advanced backside illumination
sensor delivers great-looking video in both bright and low-light
settings. And in dark environments, you can brighten the scene with the
built-in LED light.
