After Steve Jobs's keynote at yesterday's WWDC conference, I got a chance to check out the new iPhone up close. Also on display was the new FaceTime video calling feature that the CEO was so proud of. Using the phone's front- or rear-facing cameras, you can call any other iPhone 4 user and chat face to face via a WiFi connection. With little delay, the calls seemed clear, crisp, and connected. Check it out in action below!
