IPhone (first generation)-fledgling

Release: macworld 2007,65438+20071October 9.

Key points: The first generation iPhone, a multi-touch screen that shocked the world.

In 2004, Apple assembled a team of more than 65,438+0,000 internal employees to start developing the iPhone. At that time, the project was named "Project Purple" and was classified as highly confidential by Apple. To this end, the internal office lines of employees' daily work are separated for various reasons, and the degree of confidentiality is exaggerated, even the senior cadres of the company do not know.

Extension 1: Steve Jobs, then CEO of Apple, initially wanted to develop a tablet computer similar to the later iPad, but later he changed his mind and decided to enter the field of smart phones.

Extension 2: When developing iPhone, Apple cooperated with AT&; T had a secret cooperation in&; T invested in the iPhone project and gave Apple great freedom to develop iPhone hardware and software. In the past, operators had very strong control over OEMs, such as the T-Mobile version of HTC G 1. In exchange, Apple promised that within four years, the iPhone in the US market will be made by AT & amp； Exclusive sales. (PS: Apple's initial partner was Cingular, and Cingular announced its cooperation with AT&; T acquired and merged with a huge sum of $46,543,809 billion)

On June 9, 2007, at 65438, Steve Jobs officially released the iPhone at Macworld 2007. The first generation iPhone is divided into 4GB and 8GB versions, and the price is $499 and $599 respectively. However, after nearly half a year, on June 29th of the same year, Apple officially released the iPhone in the United States, which may be the originator of PPT mobile phones. As for users in Britain, Germany and France, the licensed version will not be available until the second half of the year, and Australian users will not be available until the spring of 2008.

The release of iPhone was not a thunder, and some media even called this smart phone "Jesus mobile phone". Thousands of Apple lovers are at Apple and AT & amp； T's retail stores line up one day in advance.

The proof of iPhone is a 3.5-inch multi-touch capacitive touch screen with five physical buttons: volume button, mute button, sleep/wake button and home button. The first generation iPhone had a chrome-plated layer, the back was mainly made of aluminum, but the bottom of the back was made of plastic, which was used to send and receive signals. The operating system of the iPhone was named "iPhone OS", but in the later upgraded version, Apple changed the system name to "iOS". Apple has stopped upgrading the first generation iPhone to support a higher version of the iOS system, and the final version is iPhone OS 3.

Evaluation: The first generation iPhone is an epoch-making product, which completely changed the way of human-computer interaction and opened a window for smart phones. However, its shortcomings are obvious: there is no 3G network, after-sales phone is hard to find, and the first generation system has no application, so it can only use the web version ... These problems have led to the high sales of the first generation iPhone, and everyone praises it, but the sales volume is still not good. "The revolution has not yet succeeded, and comrades still need to work hard."

Iphone 3g- minor repair

Release date: July 2008 1 1

Key points: 3G network, white body, application store.

The internal structure of iPhone 3G is similar to that of the previous generation, but some modules are added, such as 3G network and auxiliary global positioning system, to further improve the actual experience. IPhone 3G has a white version for the first time, and the body material has changed from a generation of aluminum alloy+plastic to all plastic, and the body buttons have also become metal.

IPhone 3G is equipped with Samsung S5PC 100 32-bit RISC ARM 1 1 620 MHz processor (down-converted to 4 12MHz), PowerVR MBX Lite 3D graphics processor and 128MB memory, which is the same as the previous generation. In addition to the 2.5G EDGE network supported by the previous generation, iPhone 3G also supports GPS navigation, 3G network and multi-frequency UMTS/HSDPA. These enhancements make the iPhone 3G network connection faster. IPhone 3G uses a 3.5 mm headphone jack and solves the problem of the special interface size of the previous generation iPhone, so most headphones on the market can be used on IPhone 3G.

At that time, IPhone 3G was equipped with the latest iPhone OS 2.0 system. Thanks to the new system, iPhone 3G has added functions such as mail push and app store, which makes the iPhone more mature. Of course, after updating the 2.0 system, the original iPhone also has these functions. However, with the passage of time, when entering iOS 4, although iPhone 3G can be updated, it can't get new functions such as wallpaper and multitasking. 2010165438+1On October 22nd, Apple released the iOS 4.2. 1 update. Since then, Apple has announced that it will no longer release system updates for iPhone 3G users, marking the end of iPhone 3G software maintenance.

Evaluation: The performance and screen of iPhone 3G have not been upgraded, but thanks to the addition of 3G network, GPS and App Store, iPhone 3G has become an "easy to use" mobile phone, setting a benchmark for latecomers. The highlight of iPhone 3G is actually the new iPhone OS. The addition of App Store, a heavy function, has opened up a brand-new ecology and created a brand-new profit model, setting an example for latecomers such as Google Play.

Iphone 3gs-s is speed.

Release date: June 8, 2009

Key points: screen, performance, camera upgrade

The screen of iPhone 3GS has been upgraded from 18-bit color to 24-bit color, which makes the screen of iPhone 3GS better display details and colors (320*480@ 163ppi). Camera pixels have been upgraded from 2 million in the previous generation to 3.2 million. In addition to pixel improvement, iPhone 3GS also adds some camera functions, such as autofocus and video recording. After upgrading iOS 4, iPhone 3GS can also be upgraded to 5x.

IPhone 3GS is equipped with Samsung s5pc 100 arm cortex-A8 architecture processor with a frequency of 833 MHz (as low as 600 MHz), PowerVR SGX535 GPU with a frequency of 150 MHz and 256 MB RAM.

IPhone 3GS is equipped with iPhone OS 3 system, and after the update of iOS 4, it has gained functions such as multitasking and wallpaper. The final version is iOS 6. 1.6.

Also from the iPhone 3GS, the iPhone finally has a licensed version. Apple chose to cooperate with China Unicom and brought the iPhone to Chinese mainland at the beginning of 20 10. However, due to policy factors, the first batch of Unicom iPhone 3GS did not have WiFi, and later the full version of iPhone 3GS was available.

Evaluation: As the subtitle says, "S is speed", the main upgrade of iPhone 3GS lies in hardware, which can be said to be the leader in the smart phone market at that time and the beginning of iPhone stacking. Even without the abnormal 500w camera like Nokia, iPhone 3GS is the most comprehensive mobile phone in the market. On 20/0/0, I bought an iPhone 3GS in Hong Kong and started my trip to Apple. It is undeniable that this mobile phone has experienced the absolute peak at that time, especially the good ecological environment is particularly attractive. I remember that I can download and play the search software in the app store all day, and all kinds of interesting applications make people love it. The iPhone 3GS has achieved great success by relying on the application store laid by the previous generation iPhone 3G and the powerful hardware of 3GS itself, and has begun to enter the field of vision of China people.

Iphone 4- god

Release date: June 7, 2065438

Key points: retina screen, self-developed SoC, front camera, double-sided glass.

IPhone 4 adopts a brand-new double-sided glass+stainless steel frame design, with the highest definition retina screen in the industry at that time and the leading 326ppi definition. With a thickness of only 9.3mm, the iPhone 4 was the thinnest smartphone in the world at that time. The screen quality of iPhone 4 has been greatly improved, with a resolution of 640,960 on a 3.5-inch screen and a pixel per inch of 326ppi, which is four times that of iPhone 3GS. Apple called it "retina display screen" to express that it has exceeded the resolution limit of human eyes. The maximum brightness of the screen is also 500 nits.

A three-axis gyroscope is added, and the chip is also switched to its own A4 chip with a main frequency of 800MHz. However, there are voices outside that the A4 chip is actually a shell-changing version of Samsung S5PC 100 on the iPhone 3GS, but Apple has never publicly acknowledged this. The Sim card has also been changed to micro-SIM (now commonly known as Zhongka).

The rear camera pixel has been upgraded from 3.2 million in the previous generation to 5 million, and back flash, 720p resolution video recording and 5x digital zoom have been added. IPhone 4 has added a 300,000-pixel front camera (called FaceTime camera), which supports recording 480p videos and FaceTime calls in addition to taking photos.

IPhone 4 is equipped with iOS 4 system, and the final version is iOS 7. 1.2.

But this excellent product also has a serious defect. IPhone 4 innovatively combines the antenna with the frame of the mobile phone, and divides the frame into two parts through two-layer injection molding to deal with cellular mobile and WiFi respectively, thus solving the problem of signal transmission and reception.

Evaluation: iPhone 4 is an epoch-making mobile phone, which brings a high-resolution screen, a better camera and even allows the mobile phone to take selfies inadvertently. Industrial design is also a leader in the industry. It is one of the most classic iPhone. The powerful configuration has been vividly played on iOS 4, and it is also very interesting to use. However, the appearance of the antenna door also cast a shadow over the iPhone 4, which dealt a heavy blow to Apple's reputation. But even so, the iPhone 4 has successfully become a generation of classics, enduring. At the end of 20 10, the author also bought the Hong Kong version of iPhone 4, which really improved by more than one step compared with the previous generation of iPhone 3GS. Fine screens and good industrial design really make people feel great happiness. Many ordinary users were also moved, and it was at this time that the iPhone began to catch fire in the mainland.

Iphone4s-the last legacy

Release time: 20 1 1 10 October 4th.

Key points: camera, Siri, A5 processor

The appearance of the IPhone 4s is almost the same as that of the iPhone 4 CDMA version, but the internal upgrade is bigger.

The rear camera pixel of the iPhone 4s has been upgraded from 5 million in the previous generation to 8 million (8 million pixels from the IPhone 4s to the iPhone 6, even though the latest iPad Air 3 is still an 8 million pixel camera), equipped with a 5P lens group, the maximum aperture is f/2.4, and the shutter speed is higher. Support 1080p resolution video recording and EIS electronic image stabilization. The processor is upgraded to Apple A5, which is Apple's first dual-core processor. The official claims that compared with Apple A4 processor, the CPU is improved by 2 times and the GPU is up to 7 times. The memory is 5 12MB like the iPhone 4.

IPhone 4s corrected the antenna problem of the iPhone 4 GSM version, redesigned the antenna position (in fact, it followed the antenna design of the iPhone 4 CDMA version), supported the automatic switching between the two transmitting and receiving antennas, and improved the download speed. The open version of iPhone 4s supports both GSM/WCDMA and CDMA networks, which means that China Unicom has achieved dual-network 3G, while mobile can only use EDGE. 3G data transmission speed can reach 14.4 Mbps HSPA+, and GLONASS support is added to the satellite system.

The built-in voice functions of the iPhone 4s include voice control and Siri. The former is a function launched from iPhone 3GS, which can be used without network. The latter is a new function of iPhone 4s, but it needs to be connected to the Internet to use, because it needs to be sent to the back-end server for processing and response. However, the iOS 5 system installed in the early iPhone 4s did not have Chinese Siri, so it is necessary to update iOS 6 to use Chinese Siri. Therefore, the early iPhone 4s in Greater China will guide the use of voice control instead of Siri. At the beginning of the release of the iPhone 4s, Siri only supported English, French and German, and then the version of iOS 5. 1 added Japanese. Siri of iOS 6 supports 19 national and regional languages, adds Mandarin, Cantonese, Mandarin and Korean for Asian regions, and supports Chinese voice input.

IPhone 4s is equipped with iOS 5 system, and the final version is iOS 9.3.5.

Evaluation: As an "S generation" product, iPhone 4s corrected the defects on iPhone 4, further improved the hardware, and continued to consolidate the dominant position of iPhone at that time. However, the appearance of the iPhone 4s has hardly changed compared with the iPhone 4, which makes the upgrade motivation seriously insufficient. IPhone 4s is also one of the few IPhone I haven't bought. However, thanks to the powerful hardware, the official system maintenance cycle of the iPhone 4s is very long (20 1 1-20 16), which can also be called a miracle machine.

postscript

1 This is the end of the section.

The day after the release of 20110 iphone4s, Steve Jobs, CEO and soul of Apple, died of pancreatic cancer. (Official press release when Steve Jobs died/press room/201110/05 Apple Board Statement/)

After Steve Jobs died, Apple changed the homepage of the website, showing a large black-and-white photo of Steve Jobs and the dates of his birth and death. The picture links to a short obituary-

"A visionary and creative genius left Apple. An outstanding and great man said goodbye to this world. We were lucky enough to know him and have sex with him, and since then we have lost a close friend and spiritual mentor. Steve left a company that only he can create, and his spirit will become the cornerstone of Apple's sustainable development. "

On the same day, Google hung a link "Steve Jobs, 1955-20 1 1" under the search bar on the homepage. If the user clicks on the Internet link of "Steve Jobs", the screen will go to the homepage of Apple's changed website. This is also the first time that Google commemorates a dead person in this way. His departure shocked the whole world, and countless people mourned spontaneously. And what happens when Apple loses its soul? Can Apple still make amazing products as before? Everyone feels sad and confused at the same time. At this point, all the burdens were handed over to the current Apple CEO who succeeded Steve Jobs: Tim Cook.
