FaceTime works right out of the box — no need to set up a special account or screen name. And using it 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 talking on a voice call with her, iPhone 4 to iPhone 4, and you want to switch to video. Just tap the FaceTime button on the screen. Either way, an invitation pops up on her 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
iPhone4 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.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.

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.
In a word, resolutionary:
By developing pixels a mere 78 micrometers wide, Apple engineers were able to pack four times the number of pixels into the same 3.5-inch (diagonal) screen found on earlier iPhone models. The resulting pixel density of iPhone 4 — 326 pixels per inch — makes text and graphics look smooth and continuous at any size.
Brilliant, no matter how you look at it
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 iPhonearound 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.
Advancements in the glass. And under it
Made from the same materials used in helicopters and high-speed trains, the Retina display glass is chemically strengthened to be harder, more scratch resistant, and more durable than ever. The glass also features an oil-resistant coating that helps keep the screen clean.The Retina display includes LED back lighting and an ambient light sensor that intelligently adjusts the brightness of the screen for optimal viewing and battery life.When you lift iPhone to your ear for a phone call, a proximity sensor immediately turns off the display to save power and prevent accidental dialing.
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.

Switch between apps quickly
The multitasking user interface allows you to quickly switch between apps. Just double-click the Home button to reveal your recently used apps. Scroll right to see more apps, then tap one to reopen it. No need to wait for the app to reload.
And pick up right where you left off
Apps can remember where you left off. So when you return to the app, you can jump right back into playing your game, reading the news, finding a restaurant, or whatever you were doing.
Listen to audio in the background
Now you can listen to audio from compatible third-party apps while checking email, surfing the web, playing games, and performing other tasks. So when you want to follow a ball game or listento music from Pandora, your productivity never skips a beat.
Get VoIP calls while using other apps.
Third-party apps such as Skype let you make voice calls over the Internet. Multitasking in iPhone 4 makes it possible to receive these Skype or VoIP calls while other apps are running, even when your iPhone is locked. And during a call, you can keep the conversation going while you switch to another task, such as checking a movie listing or reading an email.
Keep GPS apps running
Apps that use GPS can continue to run in the background. Not only do they constantly update your position, they can also give you spoken turn-by-turn directions even as you listen to music (the music volume lowers while the directions are spoken). It’s perfect for social networking apps, too. Now you and your friends can find each other even when you’re not actively using the app.
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.
Edit video right on iPhone
No need to wait until you’re back at your computer to edit video. You can perform basic editing right in the Camera app. Just drag to select start and end points on a filmstrip.
Tap to focus video.
Say you’re recording a scene with subjects in both the foreground and the background. How do you make sure the camera focuses where you want? Just tap that part of the image on the iPhone 4 display. The camera immediately focuses on it and adjusts exposure to match the lighting. When you want to focus on another part of the scene, just tap again.
Never miss a photo opportunity. The 5-megapixel camera built into iPhone 4 — with optional HDR setting — captures amazingly detailed images. A built-in LED flash illuminates low-light scenes. And the 5x digital zoom gets you closer to the action. You can even shoot self-portraits with the front camera.
HDR photography
Now you can take great photos that capture a wider range of light intensity using the new high dynamic range (HDR) setting. After selecting HDR, just point iPhone 4 at your subject and shoot. iPhone 4 automatically captures three photos of the scene — each with different exposure levels. Then iPhone 4 layers the shots together to create a single photo that combines the best elements of each shot and more accurately represents the wide range of light in the scene. Both the regular shot and the HDR photo appear in the Camera Roll.
Built-in LED flash.
At a candlelit dinner, on the beach at night, or wherever the light’s not bright, you can still get great shots with iPhone 4. The advanced backside illumination sensor allows you to shoot low-light photos that are brighter and clearer than ever before. And iPhone 4 now includes a built-in LED flash that automatically fires when it’s needed.
Share your photos
Send photos via email or MMS from the Camera app. Or post them directly to your MobileMe gallery, where friends and family can browse and download them. Every photo you take is geotagged with information about your location, which you can save to your computer and share with iPhoto, Aperture, Flickr, and other compatible applications and services.
