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.

excellent device!!!iPhone 4 is thinner, shorter and ever so slightly heavier than iPhone 3GS. Gone is the curved plastic back plate, replaced by a flat glass panel and a shiny metal band that wraps around the perimeter of the device. This is the first major redesign since the original iPhone debuted three years ago. The basic design - touchscreen and single front-panel button - is the same as it's always been, but the styling cues, accents, and overall hand feel are markedly changed.Most striking is the screen, which has a new sharpness from its special 3.5-inch Retina display that gives a 960×640 resolution – the highest of any smartphone. The camera, featuring 720p HD video recording, appeared to be much better quality – it has a five-megapixels sensor, compared to three on the 3GS, and features an LED flash that also doubles as a video light when recording.
Running the new 4.0 software and with an A4 Apple processor inside, response times seemed markedly faster than its predecessor.
If you’re a gamer, you will appreciate the addition of a gyroscope to the iPhone’s motion-sensing capabilities, and if you are just a general user, improved battery life that allows up to 10 hours of internet browsing on Wi-Fi means the iPhone will still be lit up and functioning long after the Evo, with its weak battery life, will have shut down.
On the bright side, FaceTime video calls are fantastic, likely because there's no cellular signal involved (you're limited to WiFi calling). Video and audio are great, it's easy to switch between front/rear cameras and landscape/portrait orientation in the middle of a call, and the narcissist in me loves flicking the preview window from corner to corner instead of paying attention to the person I'm FaceTiming with. Apple was incredibly smart to make video calling "just another button" in the standard phone interface, making it much easier to place a video call on an iPhone than a comparable Android device. The limitation with FaceTime, of course, is that for now you can only make video calls between two iPhone 4s. But that's kind of the point, from Apple's perspective.
Usually I wrap up phone reviews by saying - or at least thinking - that a week or two with a new smartphone is hardly enough time to get to know it, let alone be able to tell how it'll hold up over the long haul. In this case I've got the opposite feeling. By now all iPhone owners are familiar enough with the operating system, the iTunes/App Store ecosystem, and the way an iPhone works that a few weeks with iPhone 4 is plenty of time to get to know the thing. The question that remains isn't how well Apple's new phone will hold up over the long haul so much as whether or not Apple will be able to fix the issues that are plaguing the device right out of the gate, or if they'll wind up as part of the cost of being an iPhone user.
