Apple iPhone 4

One-tap simple.

FaceTime works right out of the box — no need to set up a special account or screen name. And using FaceTime is as easy as it gets. Let’s say you want to start a video call with your best friend. Just find her entry in your Contacts and tap the FaceTime button. Or maybe you’re already on a voice call with her and you want to switch to video. Just tap the FaceTime button on the Phone screen. Either way, an invitation pops up on her iPhone 4 screen asking if she wants to join you. When she accepts, the video call begins. It’s all perfectly seamless. And it works in both portrait and landscape modes.

Two cameras made for video calling.iPhone 4 has two built-in cameras, one on the front above the display and one on the back next to the LED flash. The front camera has been tuned for FaceTime. It has just the right field of view and focal length to focus on your face at arm’s length. So it always presents you in the best possible light.

Share what you see with the back camera.Imagine your sister is away at school and can’t make it to your son’s birthday. So you’re cheering her up with a FaceTime call. As the cupcakes come out, your son’s eyes light up, and you just have to share it. Tap a button, and before you can say, “Make a wish,” iPhone 4 switches to the back camera, and to the birthday boy's big moment. Another tap switches back to the front camera and to you. Simple, fast, and fun.

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.* This smarter approach to multitasking is available only on iPhone.

Retina Display:Thanks to the Retina display, everything you see and do on iPhone 4 looks amazing. Text in books, web pages, and email is crisp at any size. Images in movies and photos are stunning at almost any angle. That’s because the Retina display’s pixel density is so high, your eye is unable to distinguish individual pixels.The iPhone 4 Retina display uses technology called IPS (in-plane switching) — the same technology used in the Apple LED Cinema Display and iPad — to achieve a wider viewing angle than on typical LCDs. Which means you can hold iPhone 4 almost any way you want and still get a brilliant picture. That’s perfect when you’re sharing photos with a friend or moving your iPhone around while playing a driving or flying game. In addition, the Retina display offers four times the contrast ratio of previous models, so whites are brighter, blacks are darker, and everything is more beautiful.
