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.
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.
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.
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 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.

Switch between apps quickly.
The multitasking user interface allows you to quickly switch between recently used 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 listen to 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.
