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.
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.
