iPhone 4- The Real Smart Phone

Face Time

Phone calls like you've never seen before.

People have been dreaming about video calling for decades. iPhone 4 makes it a reality. With the tap of a button, 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. No other phone makes staying in touch this much fun.

1.One-tap simple.

FaceTime works right out of the box — no need to set up a special account or screen name. And using FaceTime is as easy as it gets. Let’s say you want to start a video call with your best friend. Just find her entry in your Contacts and tap the FaceTime button. Or maybe you’re already on a voice call with her and you want to switch to video. Just tap the FaceTime button on the Phone screen. Either way, an invitation pops up on her iPhone 4 screen asking if she wants to join you. When she accepts, the video call begins. It’s all perfectly seamless. And it works in both portrait and landscape modes.

2. Two cameras made for video calling.

iPhone 4 has two built-in cameras, one on the front above the display and one on the back next to the LED flash. The front camera has been tuned for FaceTime. It has just the right field of view and focal length to focus on your face at arm’s length. So it always presents you in the best possible light.

3. Share what you see with the back camera.

Imagine your sister is away at school and can’t make it to your son’s birthday. So you’re cheering her up with a FaceTime call. As the cupcakes come out, your son’s eyes light up, and you just have to share it. Tap a button, and before you can say, “Make a wish,” iPhone 4 switches to the back camera, and to the birthday boy's big moment. Another tap switches back to the front camera and to you. Simple, fast, and fun.

The Future is in the details

When creating iPhone 4, Apple designers and engineers didn’t start with a clean sheet of paper. They started with three years of experience designing and building the phones that redefined what a phone can do. iPhone 4 is the result of everything they’ve learned so far. And it’s all contained in a beautiful enclosure a mere 9.3 millimeters thin, making iPhone 4 the world’s thinnest smartphone.

1.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.

2.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. IPS technology also provides excellent color and contrast from almost any viewing angle.

3.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.

4.Apple A4 Processors

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.

5.Gyro and 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.

6.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. 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.

7.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. This dual-mic noise suppression helps make every conversation a quiet one.

8.Multi-Touch

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.

i OS 4

The World's most advanced mobile operating systems

With its easy-to-use interface, amazing features, and rock-solid stability, iOS — Apple’s mobile operating system — is the foundation of iPhone. And even as other phones try to catch up, the technologies and features built into iOS 4 keep it years ahead of the competition.

1.Elegant and intuitive interface.

The first time you pick up an iPhone, you know how to use it. That’s because the revolutionary Multi-Touch interface in iOS was designed for the most natural pointing device ever: your finger. So whether you’re using one of the built-in apps or one of the over 200,000 apps and games available from the App Store, you control everything with a tap, drag, swipe, pinch, flick, or twist of your fingers. Even tasks that might seem complicated — such as starting a FaceTime call or editing a video with iMovie — are simple, easy, and fun.

2.Hundreds of amazing features.

The features included with iOS 4 make iPhone powerful, innovative, and a pleasure to use. Here are just a few.

Multitasking

iOS 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.* This smarter approach to multitasking is available only in iOS 4.

Folders

Folders are the best way to keep your apps organized and easily accessible. To create a folder, you simply touch and hold an app until it wiggles, then drag it on top of another. iOS 4 automatically assigns a name to your folder based on the category of the apps inside it, or you can choose your own name. To access your apps, just tap the folder to bring up its contents, then tap the app to open it. Simple.

FaceTime

iOS 4 and iPhone 4 together make video calling a reality. With just a tap, you can see your friends and family while you talk to them — iPhone 4 to iPhone 4 over Wi-Fi. It works right out of the box, with no setup or special accounts needed. FaceTime is just another way iOS 4 seamlessly integrates hardware and software to make every iPhone feature as easy to use as it is groundbreaking.

3.The world’s largest app platform.

With over 200,000 apps in practically every category, iOS 4 is the platform for the world’s largest collection of mobile apps. Apple gives third-party developers a rich set of tools and APIs, and they’ve been creating apps and games that redefine what a mobile device can do. Where to find these apps? Just browse the App Store from your iPhone and download them with a tap.

4.Performance and stability that lead the industry.

iOS 4 is a desktop-class OS that’s been reinvented for mobile devices. Because it’s based on the world’s most advanced computer operating system — Mac OS X — performance in iOS 4 is fast and stability is rock-solid. iOS 4 manages power efficiently and delivers the best possible battery life. And multitasking — using multiple apps at the same time — in iOS 4 doesn’t slow down the performance of the foreground app or drain the battery unnecessarily.*

5.Hardware and software made for each other.

Because Apple makes both the iPhone hardware and the operating system, everything works together seamlessly and intelligently. This integration enables apps to take full advantage of iPhone hardware features such as the Retina display, the Multi-Touch interface, the accelerometer, the three-axis gyro, GPS, accelerated graphics, and more. FaceTime is a perfect example. It uses both iPhone 4 cameras, the display, one of the two microphones, and your Wi-Fi connection. If you’re on a voice call with someone and want to start a video call, FaceTime switches mics, turns on the front camera, and verifies your Wi-Fi connection — quickly and invisibly.

6.Safe and secure by design.

iOS 4 is highly secure from the moment you turn on your iPhone. All apps run in a safe environment, so a website or app can’t access data from other apps. iOS 4 supports encrypted network communication to protect your sensitive information. Optional parental controls let you manage iTunes purchases, Internet browsing, and access to explicit material. To guard your privacy, apps requesting location information must get your permission first. You can set a passcode lock to prevent unauthorized access to your phone and configure iPhone to delete all your data after too many unsuccessful passcode attempts. And in the event your iPhone is lost or stolen, a MobileMe membership allows you to find your iPhone on a map and remotely delete all data. If you get it back, you can restore everything from your last backup.

7.Ready for business.

Businesses around the world are choosing iPhone for its enterprise-ready features and powerful security. iOS 4 works with Microsoft Exchange and standards-based servers to deliver over-the-air push email, calendar, and contacts. iOS 4 protects your data by encrypting information in three separate areas: in transmission, at rest on the device, and when backed up to iTunes. You can securely access private corporate networks through industry-standard VPN protocols. And companies can easily deploy iPhone across an enterprise using configuration profiles.

8.Accessible by everyone.

iOS 4 comes standard with a wide range of accessibility features that help people with disabilities experience everything iPhone has to offer. For example, the built-in VoiceOver screen-reading technology allows those who are blind or have low vision to hear a description of the item they’re touching on the screen. iOS 4 also offers out-of-the-box support for over 30 wireless braille displays and many other accessibility features, such as dynamic screen magnification, playback of closed-captioned video, white on black text, and more.

9.Works the world over.

iPhone and iOS 4 are made to be used around the world. The user interface is localized into 34 languages, and you can easily switch between them. Because the keyboard is software-based, you can select from over 40 different layouts with support for language-specific features including diacritic marks on characters, handwritten input for Chinese, and contextual character options for Japanese. In addition, the built-in dictionaries support 37 language and dialects, VoiceOver reads screens in 21 languages, and Voice Control understands 24 languages.
