Apple has usually been able to run alone when setting the standard in the world of smartphones. In recent years, however, other companies have caught up with their own research and development of handsets and put some pressure on Apple. The iPhone, Apple’s bread and butter, continually receives updates to keep the company ahead, and it has been released as the iPhone 4 to an eager public.

The iPhone 4 features some changes on the inside from previous models. Replacing the Samsung-based Cortex CPU in the 3GS, iPhone 4’s predecessor, is Apple’s own A4 chip. Those in the know will recognize this as the same chip found in the iPad. While the iPad boasts 1GHz of speed with the A4 processor, the iPhone 4 doesn’t quite reach those heights. This is not to say the phone is slow by any means. It renders graphics quickly and navigates smoothly. Users who are looking for a high performance phone have nothing to worry about.

Those quickly-rendered graphics are displayed on a 3.5 inch screen with 960 x 640 pixel resolution. Combine that with a mind-numbing 326 ppi pixel density and you have a display that is absolutely second to none. The incredible resolution makes up for any shortcomings in size, and it has even earned the name of Retina Display. It is so named due to the claim that it presents graphics in more detail than the human eye is able to distinguish. It may seem like overkill to present clarity that the user can’t see anyway, but at least consumers need not worry about a less than stellar display. In fact, many testes of the iPhone 4 have stated that the Retina Display easily provides the sharpest images they’ve yet seen.

With a display so sharp, one would hope that Apple has improved on the rather weak 3 megapixel camera found on older models. They have, as the iPhone 4 features a 5 megapixel camera with a backside-illuminated sensor that is more light-sensitive. The LED flash is one of the smaller sizes and can blow out some photos, but the iPhone takes terrific photos in low light and without a flash.

Finally, Apple has decided that it is time to produce a phone that allows multitasking. Though not backgrounding in the strictest sense of the word, the iPhone lets some APIs that imitate backgrounding to run simultaneously. Critics will cry foul, but for regular, everyday users, it is just fine. Until now, Apple has stated that their smartphones would suffer battery drain by performing multitasking. The iPhone 4 has cleared up any potential issue here, as it has been known to produce almost 40 hours of normal use in some tests.

The iPhone 4 has placed Apple at the forefront of smartphone technology once again. Featuring a Retina Display unmatched in the industry and improved performance over older models, Apple’s iPhone 4 is a standard setter. Customers will be thankful for the efforts.

What’s the big deal behind the Apple iPhone? It’s expensive. It’s revolutionary. But are its features worth the money?

With all the popularity, you can assume everyone’s at least heard about it. What does the Apple iPhone feature and what can it do?

#1: Multi-Touch Technology

The most outstanding feature is the iPhone’s radical multi-touch screen. The MT screen allows any mechanical button to appear on this high tech toy. It simply allows you to use your fingers to operate it. This is contrary to any other phone today, which either have mechanical keyboards or a stylus.

By tapping the screen with your finger, you can navigate menus, dial phone numbers, write e-mail messages and likewise use the whole functionality of the popular gadget. The three-point-five-inch screen displays a keyboard for inputting text via multi-touch. Most consumers are seemingly skeptical about typing with the virtual keyboard, but Apple has predicted the common problems and has made sure the iPhone was constructed with features like automatic spell check and word prediction, not to mention an enhanced customizable dictionary. More so, the iPhone addresses the problems of typos commonly known to multi-touch usage by adding self-correction capabilities.

When scrolling, the usual wheel is not found at the side of the gadget. The multi-touch screen functionality allows its owner to scroll by dragging a finger in the desired direction. The speed of scrolling is designed to be proportional to the speed at which you drag your finger.

The multi-touch feature furthermore enables several more functions like multi-touch sensing for magnifying or reducing photos and even web pages. Using this feature, you can regulate object size simply by placing two fingers at the side of the object and then moving them, by dragging, either further apart or closer to one another. This feature does not distort images because images are initially scaled according to its original dimensions in the first place.

Hands down, the iPhone is more intelligent than any other phone today.

#2: Revolutionary Sensors

The gadget’s sensors have the ability to detect changes to the iPhone’s environment. The sensors are minuscule yet absurdly powerful. The three major sensors include an accelerometer, sensor for ambient light, and a proximity sensor.

The accelerometer sensor conveys the ability to detect any changes in the iPhones positioning. …The iPhone’s screen display will actually rotate to portrait or landscape, while still packing its contents into the 3.5-inch screen. Because it changes the view according to ratio, images are not distorted among web pages, videos, or photos.

The proximity sensors.

These high-tech features detect the location of the iPhone with regard to the skin. When you make a call and hold the iPhone up against your ear, the display will automatically set to standby. This is important in that it serves two basic functions.

One, by shutting off the display when not necessarily needed, this saves your battery’s life. More so, this avoids accidental touches to the screen, which would otherwise be sensitive. As soon as the cell is moved away from your face, the proximity sensors react in this way.

Ambient light sensor.

Through the AL sensor, changes in the phone’s environment are detected and instantaneously adjust the display’s brightness. Your iPhone’s display will always be well adjusted in regard to lighting.

#3: Mac OS X Operating System

The hype behind the Apple iPhone increased when Mac fans found out the Mac OS X would be included. The Mac OS X is the operating system inside the latest Apple computers. On the other hand, the electronic doesn’t have the complete functionality of the operating system. The entire OS X is too large to fit within the 4GB or 8GB internal memory. The iPhone contains a 500 MB version of the operating system.

The new ‘Retina’ display, so called because it is made up of more of pixels than the human retina can process, significantly improves the sharpness and clarity of images. The phone’s screen also uses the same in-plane switching (IPS) techniques as are used on the screens you will find on iMacs and iPads. Consequently, not only is the display bright and colorful, it has a massive viewing angle, meaning that it looks great no matter which way you hold it or which angle you are looking at it from.

The Apple iPhone 4 contains the company’s A4 CPU. This is the same processor found in the Apple iPad. Running on the iOS 4 operating system, a number of capabilities are available to the Apple iPhone 4. The recently renamed iOS 4 provides the long-awaited multitasking function. Just as with the welcome and long awaited copy and paste feature, Apple has come through by making the multitasking feature operate without a hitch.

Size advancements and the addition of multitasking are not the only achievements of the iPhone 4. Advancements in camera and video recording devices are also a welcome improvement. The camera found on the back has changed from 3 megapixels to a more robust 5 megapixels with the same size pixel. An LED flash and a backlit sensor augment the camera. It also comes with and integrated 5X zoom. Video can now be shot in high definition at 720p and 30 frames per second. Additionally, the tap-to-focus feature found on the camera is now available on the video recorder.

Anyone who owns an iPhone or iPhone 3G should consider the iPhone 4 a must own. Including design changes that are pleasing to the eye, the iPhone 4 has made technological advances that improve its performance as well as its imaging capabilities. These changes make it a noticeable upgrade to previous incarnations of the iPhone.
