Well, from the day Apple announced its iPhone 4, the device is capturing the front page of technology news. We can expect this handset in India by fourth quarter of 2010 and would cost you around 40K. Considering such a hefty amount, is it worth buying it? I am not sure if its worth or not, but its a engineering masterpiece. Apple engineers has designed this phone with unique features, that makes it first on any mobile device in the world. Today lets see a few hardware features that are unique to the iPhone 4.
Engineered Glass
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.
Retina Display
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.
Stainless Steel Band
Created from our 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 A4 Processor
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.
Gyro + Accelerometer
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.
Camera + LED
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. And on the front of iPhone 4, the built-in camera is perfect for making FaceTime calls and shooting self-portraits.
Mic + Speaker
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.
