At just 9.3mm, the iPhone 4 is thin as a rake but the front and back are 30 times stronger than the usual plastic. Reason - aluminosilicate glass, the stuff that windshields of military choppers are made of. The periphery is customized alloy, 5 times stronger than steel. Your accidental dropping won’t hurt your pocket-communicator. The Retina Display packs in 4 times the amount of pixels (326 per inch) of iPhone 3, and makes the text and images slicing sharp. Thanks to the added 960 x 640 pixel screen watching of HD movies on the iPhone 4 becomes a gasp. When you become a shutterbug behind the iPhone 4 camera, you shoot 5 megapixel images and high-definition videos at 720p resolution, with the LED flash and autofocus that make things easier. Opt for the iMovie video editing software, and you become a movie maker. If you happen to have Wi-Fi around, the FaceTime feature gets you into true worldwide video chat and ‘staying in touch’ becomes real personal. And all it takes to choose between the front and rear camera is a tap. The 3-axis gyro, when coupled with accelerometer, results in 6-axis motion sensing, and that’s as good as it can ever get for gaming on a cell phone. With 7 hours of talk time (3G)/10 hours of video/40 hours of audio, the iPhone 4 packs in enough power to let you do fast multitasking and then some more.
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.
