New Apple iPhone Top Guard class

Three years ago, Apple has not been in the field of mobile communications in general. Since then his iPhone game, change the smartphone itself, the most influential in the world. Well, on June 24, the company is the fourth generation of the device, the iPhone-called fourth
Although attractive Smartphones regularity of its competitors, a new iPhone deserves special attention for two reasons. First, the device in the center of a vast ecosystem of 225,000 applications, sells most popular gadgets such as Apple iPod, media player and a tablet connected IPAD to nearly 100 million units. Secondly, multi-touch interface on the iPhone is a browser-based movement elegant with sophisticated music and video playback and other features have been imitated by many competing products, so Apple does not affect all industries.

I tried the iPhone 4 for more than a week. In both hardware and software, is a big step from its predecessor, the outstanding, the 3G iPhone.

Has some disadvantages and limitations, especially overwhelmed AT & T network in the United States, spoke in my tests, the new phone sometimes better, and unfortunately sometimes worse than its predecessor. I'll go into the background. But overall, Apple (AAPL) has a great update, well designed, conducted in my opinion, is ahead in the smartphone wars.

The iPhone 4 is a dramatic revision. He manages to grab a radically screen network, a second camera, facing the front and a bigger battery, better rear camera with flash and a faster processor in a body that is 24% thinner, slightly narrower and preserves same length and weight than its predecessor. In fact, says the Apple iPhone 4, the thinnest smartphone in the world and the world sports smartphone screen with higher resolution.

With the camera on the face and intelligent software called face time, Apple has a simple video calling and high-quality, mobile phones, although so far only Wi-Fi and iPhone homeowners only fourth on several tests, this feature worked very well for me and is a classic example of the value with an integrated hardware and software.

In addition, the iPhone is now an updated operating system, which also featured free business model, software features, such as limited multitasking (the ability of applications running on the same installation time) , folders and applications related to e-mail, a unified inbox for multiple accounts and the possibility of messages as threaded conversations before. This software is called iOS4.

The iPhone 4 is the same price as the iPhone 3G costs $ 199 for a model with 16 GB and 32 GB for $ 299 with a two-year AT & T (T). The 3G model at $ 99 with a drop of two years and 8 gigabytes of memory.
Design

Physically, the iPhone 4 attractive and feels good in your hand. The rear panel is glass, which Apple says is a variety Super Strong 30 times harder than plastic covers. I had several times by a few feet above a hard, smooth, and won no scratches at all during my tests, even if I have a case or get damaged.

Although the same weight as its predecessor, the iPhone 4 is denser and stronger, more like a disposable gadget that's fine. It still looks like an iPhone but managed to get the 3G bulb compared.

Although the 3.5-inch screen, once seen as a giant, is now smaller than some other smartphones, high-resolution packages in a lot of things and makes the text appear almost like the ink on the beautiful paper . The software is simply richer and softer job seekers competing phones I tested, with less confusion and setup menus, applications and more.
Screen, voice, percussion, and the camera

always brilliant marketing, Apple has described its new screen retina. "In a resolution of 960 × 640, has four times the pixels of its predecessor and has a large 326 pixels per inch. Nobody knows how it compares to the retina of man, but I know that, as claimed by Apple text on the screen will show a dotted line, but enlarged to giant size.

Voice quality is very good, the speaker was excellent in long discussions, and performance data via Wi-Fi. Video and audio streaming from the Internet has played without problems.

Apple says the battery life for most of the functions of seven hours of talk time, compared to five hours in the previous model. I have no specific test battery, but also an intensive, 4 of the iPhone's battery has never been the red zone in a single day of my tests reached.

The new camera is another important benefit. My test shots were crisp and clear, even in low light and close-ups. This is not the best camera phone I tested, but it is a big improvement.

IPhone 4 records video in high definition, and in my tests, these videos were very good in most conditions. Apple is also on sale for $ 5 at the iPhone version of its Macintosh iMovie video editing software for video editing.
FaceTime

Video telephony is one of the best features of this device. As already mentioned, there is currently no iPhone Wi-Fi 4 and at both ends, if Apple says it is free of technology to another, and expects millions of compatible devices. No installation and nothing to learn. Just push a button face time, and if the other person accepts the invitation to speak face to face, her image appears in your own image in a small corner window.

You can select an icon on the screen to change the camera in front of the rear wheel, so you can see your caller in the room, or even other people in your area, behind the phone.

You can even make a video call as an audio cell call, press a button and switch the Wi-Fi calling FaceTime. It worked for me a large margin of a few short sentences.
Multitask

After years of complaints, Apple iPhone finally multitasking. But is limited in scope, not please everyone did. 4 On the iPhone, multitasking is not all applications can run completely in the background. To avoid the devastating drain on the battery life Apple has some applications, multi-tasking support. These include audio streaming services like Pandora to keep playing music on the Web while you do other things and follow the navigation voice applications that work while having a conversation. Others who work full background includes Internet telephony applications, and those who work long downloads.
However, some logical candidates, as Twitter and Facebook, but if you change to break a distance. You can return quickly, and is updated faster than before, but they are constantly updated in the background. You wake up in the background when you set it to notify you of an upgrade, and only for a limited time. Apple said that to get regular updates from hundreds of social networks in the background to kill the battery very quickly.

In fact, for many scenarios, such as games, Apple's version of multitasking is really fast switching between open applications store, which in its place. And even achieve this, applications must be updated. For some users this short version of multitasking is a disappointment.

To use multithreading, you just hit the iPhone home button twice and display a series of application icons. Click on the desired and if you have upgraded to the new operating system will appear as you left.

Multitasking also updated work on the iPhone 3G models, but not for older models.
Folder

Because iPhone users can collect hundreds of applications, can be difficult to arrange. Thus, the new iPhone OS, now you can group them into folders. For example, I found the application icon in the Wall Street Journal, which has dragged on top of an application to the Washington Post, and a file was created and immediately called "news" related to the applications' built-in classes. You can name what you want, or to alter or delete files.
The main disadvantage

The main drawback of the iPhone 4 is that the United States has chained to AT & T, which operates not only a network connection problems and maintenance of calls in many cities, but the data now unlimited flat rate plans abandoned. Apple needs a second network.

Both Apple (AAPL) and AT & T (T), said he worked for the iPhone 4 do a better job with the network of AT & T. For example, the phone itself surrounded by a road, finished in stainless steel, which acts like a huge antenna. In addition, Apple has said that he also hears the phone trying to understand what the position of the tape to the network less congested and less disturbed by interference, the quality of a signal on his brute strength. AT & T said it made some changes to its network with the new iPhone in mind.

But in my tests, the network was a bit of everything. Compared to its predecessor, the new iPhone has a little less the calls I made in my car, both in Washington and Boston, and was much stronger and clearer in my car built-in Bluetooth handsfree system.

But in places where the signal is relatively weak, the iPhone 4 were not bars, pubs or less than its predecessor. Apple says that to fix it, and it was a mistake, and that has to do with the way the bar is displayed, and no real ability to make a call. And indeed, in almost all cases, the iPhone 4 in a position to make calls even though the bar was missing.

However, at least six times during my tests, the new iPhone has been declared a "No Service" or looking for a network, while the first, on the other hand, showed at least a few bars. Neither Apple nor AT & T was able to explain. The iPhone 4 recovered quickly in these situations, public administration after a few seconds, but still worrisome.

Like its predecessor, I can not recommend this new iPhone for voice calling people bad experience AT & T coverage, if they are willing to accept a second phone on a network that are best for them.

For everyone else, but I'd say Apple is a smart phone that works very well, adds impressive new features and is generally the best camera in this class Gebauer
