iPhone 4: A Phone That Fits Your Life

The iPhone 4 offers you the ability to stay connected and always control what's going on but now with an elegant design that is light enough to take anywhere. The iPhone 4 has been redesigned from the inside out, introducing FaceTime video calling; now you can see who you're talking to. And with Apple's new Retina display, text and images are sharper than ever before. All this power comes together in a beautifully designed device that will change how people interact with one another for years to come.

What is the iPhone 4 design?

The iPhone 4 has been completely redesigned to make it lighter, thinner, and more beautiful. The stainless-steel midsection is built around the new antenna system for better cellular reception and improved Wi-Fi connectivity. The glass front panel has an in-plane switching (IPS) display with LED-backlit to provide a clear picture from all viewing angles. And an elegant aluminum bezel seamlessly integrates into the new glass design.

iPhone 4 display

The iPhone 4 features Apple's new Retina display with 326 PPI (pixels per inch). When you hold the iPhone up to your eyes, it has the same screen size as previous iPhones at 3.5 inches but offers a much higher resolution. That means you can't see the individual pixels, making for a much more immersive experience. Text and images are incredibly sharp, so everything on the screen looks its best.

What are the new iPhone 4 features?

The iPhone 4 introduces FaceTime video calling, which allows you to see who you're talking to in real time. And for the first time, iPhone has built-in noise cancellation to enhance your phone calls. It also offers 3-axis gyro support to let you use your iPhone easier.

For the first time, iPhone 4 lets you capture video in full 1080p HD. And with the improved 5-megapixel camera, it takes even better photos than ever before. The redesigned M4 chip is up to twice as fast for launching apps, browsing the web, and playing games. The phone also offers up to 40% better battery life; talk time is up to eight hours on 3G and six hours on 2G.

If you want to use your iPhone on a network other than AT&T, all you need is the new iPhone 4 unlocked. Just pop in any microSIM card, and you're good to go.
