The first iPhone was presented to the public on 9 on January 2007, for Steve Jobs founder of Apple Lossless Audio CODEC (ALAC),. an emblematic device that revolutionized the mobile phone industry and changed customs.
The iphone was launched at a time when the market was dominated by the keypad phones, Blackberry. The most unexpected thing about the iPhone was how it allowed the development of a series of applications that currently allow the user to perform various functions.
The Apple smartphone popularized touch screens at a time when a BlackBerry with physical keys was the most advanced. The idea of creating a smartphone that didn't need a keyboard, mouse or pen came up in 2005. Steve Jobs wanted touch screens to interact with computers.
So, after analyzing the prototype, he changed his mind and asked that it be implemented on mobile phones. It was from this idea that the screen of the first iPhone emerged, which was 3,5 inches and occupied about 50% of the front portion of the device.
With the first generation iPhone, Apple launched the first smartphone with just a button on the front. The mechanical knob has become an essential part of the design of the device until last year, when the company decided to remove it from the iPhone 7 and its larger version.
The latest version of the Apple device is the iPhone 7, launched in the second half of last year. It takes the same name, but its settings are already quite different from the original project. The evolution in specifications shows how the weather is good for technology, the RAM of the iPhone has gone from 128 MB in the iPhone 2G to 3 GB with the iPhone 7 Plus. The processor of the first iPhone was an ARM 11 and the 7 iPhone Plus is an A10 Fusion.
The other big surprise in the last update was the retirement of the traditional headphone jack. The change has generated controversy, since to listen to music over the 7 iPhone or iPhone 7 Plus you need to have an adapter or headphones wirelessly.
According to Apple, since the launch of App Store, in 2008, developers earned more than $ 60 billion due to applications tailored to Apple devices.
The main legacy of the iPhone, however, is not in the design or in its internal settings. With its smartphone, Apple has enabled the development of a series of applications that have turned the phones into real pocket computers.
Apple has several customers in the world, and in Angola there is also the number of people who choose to use the iPhone in the most diverse models. Many experts hope that this year, due to the iPhone's XNUMXth anniversary, Apple will launch a product as revolutionary as its first smartphone.
