Apple announced the iPhone 4 at its Worldwide Developers Conference earlier this month. After the customary hype that followed, iPhone 4 will hit stores Thursday morning, though some customers who have ordered the device will receive them earlier. Judging by 600,000 early orders, iPhone 4 is already a runaway hit.
Buyers won't be disappointed. The killer feature is what Apple calls FaceTime video chat. The promise that you and the person you're talking to on a phone can gaze into each other's eyes dates back to when LBJ occupied the White House. No one has really nailed video calling through the years, at least not the way Apple has nailed it here, with certain limitations. FaceTime is as simple as making a regular call. To help to accomplish this neat stunt, iPhone 4 adds a front-facing camera that complements the more traditional, and improved, camera on back.
