While everyone else was busy trying to keep up with iPhone, Apple were busy creating amazing new features that make iPhone more powerful, easier to use, and more indispensable than ever. The result is iPhone 4. The biggest thing to happen to iPhone since iPhone. All the breakthrough technology in iPhone 4 is situated between two glossy panels of aluminosilicate glass - the same type of glass used in the windshields of helicopters and high-speed trains. Chemically strengthened to be 20 times stiffer and 30 times harder than plastic, the glass is ultradurable and more scratch resistant than ever. It's also recyclable. The 960-by-640 backlit LCD display boasts a pixel density of 326 pixels per inch, making it the highest-resolution phone screen ever. To achieve this, Apple engineers developed pixels so small - a mere 78 micrometers across - that the human eye can't distinguish individual pixels. That makes text remarkably sharp and graphics incredibly vivid. IPS technology also provides excellent color and contrast from almost any viewing angle. Created from Apple's own alloy, then forged to be five times stronger than standard steel, the CNC-machined band is the mounting point for all the components of iPhone 4. The band provides impressive structural rigidity and allows for its incredibly thin, refined design. It also functions as both iPhone 4 antennas. Apple engineers designed the A4 chip to be a remarkably powerful yet remarkably power-efficient mobile processor. With it, iPhone 4 can easily perform complex jobs such as multitasking, editing video, and placing FaceTime calls. All while maximizing battery life. iPhone 4 includes a built-in three-axis gyroscope. When paired with the accelerometer, it makes iPhone 4 capable of advanced motion sensing such as user acceleration, full 3D attitude, and rotation rate. Translation: More motion gestures and greater precision for an even better gaming experience. The iPhone 4 camera shoots gorgeous 5-megapixel photos and stunning HD video. And with its advanced backside illumination sensor, it captures beautiful images even in low-light settings. The built-in LED flash does double duty. When you're taking pictures, it works as a flash. When you're shooting video it can stay on to light up the scene. And on the front of iPhone 4, the built-in camera is perfect for making FaceTime calls and shooting self-portraits. While most phones have only one microphone, iPhone 4 has two. The main mic, located on the bottom next to the dock connector, is for phone calls, voice commands, and memos. The second mic, built into the top near the headphone jack, is for FaceTime calls and for making your phone calls better. It works with the main mic to suppress unwanted and distracting background sounds, such as music and loud conversations. This dual-mic noise suppression helps make every conversation a quiet one. With its large Multi-Touch display and innovative software, iPhone lets you control everything using just your fingers. How does it work? A panel laminated on the glass senses your touch using electrical fields. It can register multiple touches at once to support advanced gestures such as pinch to zoom, two-finger tap, and more. The panel then transmits the information to the Retina display below it.
FaceTime People have been dreaming about video calling for decades. iPhone 4 makes it a reality. With just a tap, you can wave hello to your kids, share a smile from across the globe, or watch your best friend laugh at your stories - iPhone 4 to iPhone 4 over Wi-Fi. And it works right out of the box. No other phone makes staying in touch this much fun.
Two cameras, two views iPhone 4 has two cameras: One on the front, which focuses on you. And one on the back, which focuses on everything else. FaceTime lets you switch back and forth between them at any time during a video call. All you have to do is tap a button.
Retina display The retina display on iPhone 4 is the sharpest, most vibrant, highest-resolution phone screen ever, with four times the pixel count of previous iPhone models. In fact, the pixel density is so high that the human eye is unable to distinguish individual pixels.
Multitasking iPhone 4 introduces a whole new way of multitasking. Now you can run your favorite third-party apps - and switch between them instantly - without slowing down the performance of the foreground app or draining the battery unnecessarily.
HD video recording and editing Shoot your own movies in high definition. Capture impressive video even in low-light settings, thanks to the advanced backside illumination sensor and built-in LED light. Then edit and create your own mini-masterpiece right on iPhone 4 using the iMovie app - with Apple-designed themes, titles, and transitions.
5-megapixel camera with LED flash Take beautiful, detailed photos with the 5-megapixel camera with built-in LED flash. The advanced backside illumination sensor captures great pictures even in low light. And the front-facing camera makes it easy to take self-portraits.
