Previously, this review made by "X360" in kaskus and originating from the Indonesian language, I just translate it into English. without wasting time again, let's see the review.. Check This Out
This time the slogan is : "This changes everything. Again"
Yes the concept of the iPhone is changing many things, but is it true iPhone4 change many things?
Here, I will not be too much to explain all the advantages of the iPhone in general,
but rather focus on discussing what distinguishes iPhone4 with iPhone3GS?
Because I believe the readers are quite familiar with the advantages of the iPhone before. Then try whatever is appointed by Apple through its iPhone4?
And if you really need to replace the iPhone 3G / 3GS you to iPhone4? I hope many of your questions answered through this article.
Let's talk about the details of the design iphone4,
At first glance iPhone4 still look elegant, but is also more formal with
a more square shape, not too loose because the stainless steel silver
enclosing.
Initially I saw iPhone4 design 'is not too apple', because usually Apple rarely
using a design that was once the dominant form of the square, look at the ipod, macbook
until ipad. So the word 'more formal' good enough to given the design iPhone4.
In size, the iPhone 4 is identical to the iphone 3g, length and width almost identical, although the iPhone has a width of 4 is slightly more minimal than the iPhone 3g:
iPhone3g with 11.5 cm x 6.2 cm, and iPhone4 with 11.5 cm x 5.8 cm. But for the size of the thin dimension iphone4 level better than iphone3g:
iPhone3g by 1.2 cm, and iphone4 by 0.9 cm, with thinness is Apple's bold claim that iPhone4 is the thinnest smartphone in existence until today. It is simply incredible thinness, but to the size of four very-heavy iPhone is identical, differing only 2gram heavier than the iphone 3g, but according to personal opinion, I think the shape of the casing design is more grip iPhone4 when held for more square shape makes it feel more lightly iPhone4 when we are very comfortable to hold.
For LCD screen coating, iPhone4 Aluminosilicate Glass using materials, this material is also used in the layers of glass that is used for helicopters and super fast trains today, supposedly his strength 30 times harder than plastic, so it can be guaranteed that the lcd screen iphone4 'Scratch Resistant', I personally strongly believe in the promise of this apple, because from my experience that they promised to use ipad scratch resistant, as far as I use without using the anti-scratch until today there is absolutely no slightest scratch even though I'm pretty indiscriminate when cleaning screen with any fabric, or tissue. Maybe it's time we believe the current apple is no longer necessary using anti-scratch on the lcd screen, because I think personally anti-scratch less iPhone4 projecting images generated by color, sharpness and contrast according to the original. But for their promise to 'fingerprint resistant' it must be proved to myself as we have held it, because when using iPhone3g or ipad, I think Apple still has not managed to overcome the problem of fingerprints on the lcd screen.
Then iPhone4 times around the casing layer is protected by Stainless Steel is made from solid alloy, Apple pledged their design alloy material five times stronger than stainless steel in general. Apple was seldom using a design that was once the dominant form of the square, look at the ipod, macbook until ipad. So the word 'more formal' good enough given the design iPhone4.

FEATURE
There are several features that are favored by Apple with its iPhone4, include the following:
- Video Call with two-sided camera
- Retina Display
- HD Video Recording
- A4 Processor
- OS4 with multitasking
From these features might arise, questions like, What's wrong with the video call? not a video call is not something new? Screen with higher resolution? 5 Megapixel camera? not many other devices that have more than all of that achievement? What's just right? why apple favor these features?
Actually all of the features provided by Apple is not really new, such as touch screen with a multitouch screen, touch screen has been there since a few years earlier, but in fact, to apply current best touchscreen multitouch Apple's remains, along with features iphone4 try seeded apple on this, but what makes the apple 'different' does not lie in innovation and creativity they alone in carrying the new concept, but Apple's most good at carrying and adapting the technology into the everyday lifestyle, moments they are always right so as to create a lifestyle of efficiency in many circles. Just tell iPhone4 a versatile HD (High Definition) is now the era of HD is growing so rapidly in the world of technology, HD video streaming on the internet, Chanel-HD channel on cable TV, etc.. iPhone4 comes with all the features of HD with every amenity to connect directly with the communities on the internet or between devices High Definition. That's just one example of which Apple did with their products.
Now I will discuss in greater detail about the features that Apple seeded one by one:
Video Call : Two sided camera
Now use the video call feature becomes increasingly simple with iPhone4 Facetime, Activate the video call with just a button provided at the time of incoming calls reads 'Facetime', just touch it you can connect directly via video call. Besides portraits, and landscape function can also choose from when making video calls. So what value is more than these features compared with the video call using another device? From what I observe in his presentation, I see philosophy brought Facetime 'Practical' in it, easy to operate, but broad in possibilities usage.
What is a retinal display?
Apple calls its latest technology with retinal LCD screen displays,it's because the resolution displayed by iPhone4 very sharp, that is 960 pixels x 640 pixels by Contrast ratio 800: 1. In the case of the visual has always apple never kidding. They also apply the technology, IPS (in plane switching) technology which is also embedded at the Apple LED Cinema Display and the iPad. Very unusual feature for a mobile gadget. With the size of the LCD screen measuring 3.5 inches, but carried the resolution to 960 x 640 I think the sharpness of the image quality will be very sharp, then with contrast ratio of the screen is likely to be small mobile devices will certainly produces bright images full of vivid colors.
Now on iPhone4 camera is also equipped with LED Flash, so there is no longer generated as a dark image on the iPhone before, no longer need to use an additional app just to add a photo brightness and contrast manually. Not only that, the camera 5 megapixelnya will be guaranteed of the best image quality, especially with LCD screen resolution iPhone4 sharp. there are features keep focus, simply by touching the desired object, then the camera will auto focus to the object, much less with a resolution of the resulting iPhone4, guaranteed the focus really 'focus', the detail of the object that we must focus more pronounced with resolution of it I feel.
As it is known that the A4 is the same processor used in the iPad, the processor has proved very efficient in executing various programs that exist in the iPhone OS, it is also rapid but relatively stable, and another good save on power. With processor speed of this kind would be very amazing if immersed in a device that is still classified in the smartphone segment. certainly exceed all expectations of the previous generation iPhone users, do not be surprised if now a variety of purposes can be made by the High Definition iPhone4 with ease, play, record, and edit HD videos is now not a problem for the A4, especially multitasking .. must be very light.
The combination of technology and lifestyle is now more perfect ....
Then how about the slogan "It changes everything. Again"?
I think with all the features of a 'upgrade' with iPhone4 offered by Apple, the slogan 'everything changes' not very appropriate, may be more appropriate if say 'it upgrades anything', indeed the concept of 'iPhone' change many things, especially in revolusionary mobile lifestyle, iPhone4 but according to my personal opinion only 'improve' mobile lifestyle has changed since the emergence of the iPhone had previously been at a higher level with all its features.
But of course it's all good there, i love upgraded!
But to change your lifestyle? I think apple is enough to change much with the emergence of the iPhone a few years ago. And that culture is still ongoing until iPhone4 this time.
That's all the advantages that I can express the iPhone4 when compared with the previous iPhone, and now back to your choice, whether you need all the features that exist on iPhone4 or you simply feel satisfied with your current device? decision is in your hands ...

HD Video Recording
Now technology has started to enter the era of hd, faster Internet speeds and rapid, video sites to the theme of all cable tv hd, apple moments in delivering the hd video recording feature a very precise , iPhone4 can record moving images at 30 frames per second with the sharpness of the image until 720p, remarkable collaboration between the processor A4, a new camera and LCD screen display that Krispy ... Apple also promises good governance automatic lighting on iphone4, so iphone4 can automatically detect and differentiate various light and dark background, so that a balance is maintained. we'll see ... A4 processor is also very supportive to perform live via video editing hd iphone4 you, do not have to bother to do editing on a PC, cut and combine video images of one another can now be done at once right after you record a video, after that you can instantly upload it to the youtube, while waiting for the upload process you can take advantage of multitasking feature to chat with your friends on facebook or playing games. WOW!!
If not satisfied with the standard video editing features, Apple also made a new app called iMovie, like adobe premiere in your devices, various kinds of special effects and sound effects in this app. and only in komersilkan less than U.S. $ 5.
Oh yes, just add, with the ability iPhone4 video display resolutions up to 720p, so if we use the connector to VGA from iPhone4 to screen LCD TV, then you could be a solution iPhone4 good as HD Video smallest player ever, you do not need anymore buy a Blueray player and HD digital video player in the market, you just need to watch HD videos collection you just using iPhone4, because iPhone4 can produce excellent images up to 1024x768 on your HD TV LCD screen.

Finally after so long awaited widely condemned at the same time, Apple launched the iPhone OS4, which also has been embedded in iPhone4, and inside there are features of OS4 was for 'Multitasking', finally ... a normal thing that a new sophisticated devices applied to the iPhone after appearing to fourth generation.
To activate this feature easy to use it ...
If you usually click the home button will remove us from the app, then to come up with enough to press the button multitasking home two times. Later a simple interface will appear that we can operate the moment we are running another app.
Fast processor allows multitasking to the app to quickly and easily.
Now with the multitasking you can do many things at once without any restrictions, such as:
- Featured voip Such Skype notification, so that incoming calls from Skype partner you can enter at any time while operating the other app.
- Gps can remain on while doing other activities, so no need to bother in and out and re-do a search and synchronization
- Push notification of any type of app everything went smoothly in the background system.
- Download / upload a video file while playing a game? it becomes possible .....
And various activities to iPhone version of your own ...
Now everything is posible, space has become more widespread and relief, the possibility of growing without any restrictions.
This feature also is one part of the iPhone OS4 which can be downloaded as an upgrade for users of the iPhone before, namely the iPhone 3GS.
This is actually a simple feature, but very, very useful for me, ever irritated looking app from the app that there are 11 pages in the iPhone / iPod Touch you? certainly ever ... one of the benefits of the iPhone is the amount of content, the owner of the iPhone / iPod touch usually have tens to hundreds of devicenya app, but the absence of foldering really very disturbing. Now foldering features presented directly on the iPhone OS4, you can create a folder that you can give your own name for the category according to your wishes, nor can also be automatic, because it can detect the type of category iphone4 app you have, all can automatically enter into folders according to categories respectively, all the games into the games, everyone can get into the app folder productivity productivity, apple had been thinking about this in detail, and wonderful again iPhone4 can create up to 180 folders, each of which accommodates 12 apps folder, so the total app can be accommodated iPhone4 is 2160app, ideal for the mania and the collector app app. detail detail little sweet.
Background interfaces can now be modified with a collection of wallpaper images, so no plain as usual, far more character and dynamic, despite the fact that circulating iphone jailbreak version later can change various interesting themes.
Actually there are many more features promoted by the iPhone OS4, but some of the best of them is that I mentioned above.
