With face time, you can talk to someone face to face when ever you are in a wifi zone. 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. 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. See more here.
