|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.|
Customer Reviews of Apple iPhone 4 32GB - Black - AT&T (Refurbished)
i love my iphone, recently i brought a new one..
great product with some problems4/27/2013
i bought this item, brand new. it worked great, as with other apple products i had. i was listening to the ipod app while walking to the store, with the iphone in my pocket. it slipped out of my pocket and fell. i thought it would hit the corner and maybe dent a corner or chip like a ipod would. but no, it fell flat on its back and shattered. i was horrified, to say the least, but what do you know, the music continued to play, the screen was fully functional, it was shatered, but i could still use the whole screen with it being usable and it did not hurt at all. it was only visual! i was amazed! bad insenent but it continued to impress! once you go mac, you never go back.
With the iPhone 4, Apple again shows that it is a powerful player in the smartphone wars. It won't be for everyone, the call quality and reception vary if you don't use a case, and AT&T's network remains a sticking point, but the handset's striking design, loaded feature set, and generally agreeable performance make it the best iPhone yet.
There is a lot of great features add to this model. Some features are limited lacking simple improvments and other features are dependent on app developers to update the apps in order to work proper. This can be fixed with a update. People just need to speak up. I think this phone is still a good phone and I think it is worth buying.
The most amazing phone5/17/2012
Everything about this phone is so much better than my previous iPhone, which I loved. Apple just keeps raising the bar with its products, which is always a good thing for consumers.
