The iPhone is the first smartphone designed and marketed by Apple Inc. It combines an iPod, a cell phone, and an Internet communications device with text messaging and visual voicemail. It also offers access to the Internet via a cellular network and Wi–Fi.

The iPhone is a line of Internet and multimedia–enabled smartphones marketed by Apple Inc. The first iPhone was unveiled on January 9, 2007, and released on June 29, 2007. The most recent iPhones, the seventh–generation iPhone 5C and iPhone 5S, were introduced on September 10, 2013. The user interface is built around the device‘s multi–touch screen, including a virtual keyboard. The iPhone has Wi–Fi and can connect to cellular networks. An iPhone can shoot video (though this was not a standard feature until the iPhone 3GS), take photos, play music, send and receive an email, browse the web, send texts, and receive visual voicemail. Other functionality, such as video games, reference works, and social networking, can be enabled by downloading mobile apps. As of January 2015, Apple‘s App Store contained more than 1.4 million applications available for the iPhone. Apple has released seven generations of iPhone models, each accompanied by one of the seven major releases of iOS. The iPhones with the A4 processor and later also have an 8 MP camera and a dual–core processor.

 

The most recent iPhone model is the iPhone 6, which was unveiled at a special event on September 9, 2014. The iPhone 5C (marketed with a stylized lowercase ‘c‘ as iPhone 5c) is a smartphone that was designed and marketed by Apple Inc. The device was part of the iPhone series and was unveiled on September 10, 2013, and released on September 20, 2013, along with its higher–end counterpart, the iPhone 5S. The iPhone 5C is a variation of the iPhone 5, with similar hardware specifications but a hard–coated polycarbonate shell instead of the metal body of the 5. The iPhone 5C was available in several color options and shipped with iOS 7. The iPhone 5C was discontinued by Apple on September 9, 2014, with the 16 GB model selling at US$450 off–contract. The iPhone 5S (marketed with a stylized lowercase ‘s‘ as iPhone 5s) is a smartphone that was designed and marketed by Apple Inc.

Part of the iPhone series, the device was unveiled on September 10, 2013, at Apple‘s Cupertino headquarters. It was released on September 20, 2013, along with its lower–cost counterpart, the iPhone 5C. The iPhone 5S is the first iPhone to be released in gold, silver, and space gray. It is the seventh generation of the iPhone. The iPhone 5S maintains almost the same external design as its predecessor, the iPhone 5 while adding new hardware features, including Touch ID, a fingerprint recognition system that can be used to unlock the phone and to authenticate App Store and iTunes Store purchases, and a 64–bit Apple A7 processor. The iPhone 5S also introduced a redesigned home button with a built–in fingerprint sensor, as well as a rear–view camera that has been increased in resolution to 8 megapixels. The iPhone 5S was officially discontinued by Apple on March 21, 2016.

apple mobile phone A mobile phone is a portable telephone that can make and receive calls over a radio frequency link while the user is moving within a telephone service area. The radio frequency link establishes a connection to the switching systems of a mobile phone operator, which provides access to the public switched telephone network (PSTN). Modern mobile telephone services use a cellular network architecture, and, therefore, mobile telephones are often also referred to as cellular telephones or cell phones. In addition to telephony, modern mobile phones also support a wide variety of other services, such as text messaging, MMS, email, Internet access, short–range wireless communications (infrared, Bluetooth), business applications, gaming, and photography. Mobile phones offering only those capabilities are referred to as feature phones; mobile phones which offer greatly advanced computing capabilities are referred to as smartphones. The first handheld mobile phone was demonstrated by John F. Mitchell

[1] and Martin Cooper

[2] of Motorola in 1973, using a handset weighing c. 2 kg (4.4 lb). In 1983, the DynaTAC 8000x was the first commercially available handheld mobile phone. From 1983 to 2014, worldwide mobile phone subscriptions grew to seven billion, penetrating 100% of the global population and reaching even the bottom of the economic pyramid.

[3] In the first quarter of 2016, the top smartphone manufacturers were Samsung, Apple, and Huawei (and “smartphone sales represented 78 percent of total mobile phone sales“).

[4] For feature phones as of 2016, the largest were Samsung, Nokia, and Alcatel.

[5] A handheld mobile radio telephone service was envisioned in the early stages of radio engineering. In 1917, Finnish inventor Eric Tigerstedt filed a patent for a “pocket–size folding telephone with a very thin carbon microphone“.

[6] Early predecessors of cellular phones included analog radio communications from ships and trains. The race to create truly portable telephone devices began after World War II, with developments taking place in many countries. These “0G“ systems were not cellular, supported few simultaneous calls, and were very expensive. The first handheld mobile cell phone was demonstrated by Motorola in 1973.

[7] The first commercial automated cellular network (ANSI–41) was launched in Chicago in 1983. This was followed in 1991 by the simultaneous launch of the Nordic Mobile Telephone (NMT) system in Denmark, Finland, Norway, and Sweden.

[8] Several other countries followed in the early to mid–1990s. These first–generation (1G) systems could support far more simultaneous calls but still used analog cellular technology. In 1983, the DynaTAC 8000x was the first commercially available handheld mobile phone. In 1991, the second–generation (2G) digital cellular technology was launched in Finland by Radiolinja on the GSM standard. This sparked competition in the sector as the new operators challenged the incumbent 1G network operators. Ten years later, in 2001, the third generation (3G) was launched in Japan by NTT DoCoMo on the WCDMA standard.

[9] This was followed by 3.5G, 3G+, or turbo 3G enhancements based on the high–speed packet access (HSPA) family, allowing UMTS networks to have higher data transfer speeds and capacity. By 2009, it had become clear that, at some point, 3G networks would be overwhelmed by the growth of bandwidth–intensive applications, such as streaming media.

[10] Consequently, the industry began looking to data–optimized fourth–generation technologies, with the promise of speed improvements up to ten–fold over existing 3G technologies.[11] [12] The first two commercially available technologies claimed to be 4G were the WiMAX standard, offered in North America by Sprint, and the LTE standard, first offered in Scandinavia by TeliaSonera. 5G is a technology and term used in research papers and projects to denote the next major phase in mobile telecommunication standards beyond the 4G/IMT–Advanced standards.[13] [14] [15] [16] [17] The term 5G is not officially used in any specification or official document yet made public by telecommunication companies or standardization bodies such as 3GPP, WiMAX Forum, or ITU–R. New standards beyond 4G are being developed by standardization bodies, but they are at this time seen as under the 4G umbrella, not for a new mobile generation.

Smartphones have a number of distinguishing features. The International Telecommunication Union measures those with an Internet connection, which it calls Active Mobile–Broadband subscriptions (which includes tablets, etc.).[18] In the developed world, smartphones have now overtaken the usage of earlier mobile systems. However, in the developing world, they account for around 50% of mobile telephony.[19] Features of a smartphone include Web browsing and emailing capability High–speed data access QWERTY keyboards Integrated cameras and camcorders Location–based services Mobile payment Advanced applications with downloadable games, stock–trading, banking, and ticket purchases Integrated sensors such as GPS, accelerometers, and proximity sensors Voice–command/voice–recognition capabilities Digital assistants such as Google Now, Siri (iOS), Cortana (Windows Phone), and Bixby (Samsung) Multi–touch touchscreens Bluetooth, NFC, and infrared connectivity An Apple iPhone 6S Plus showing its rear–facing camera, headphone jack, and Lightning connector The earliest commercially developed cellular network was the 1G Generation Zero mobile phone system, created in Japan in 1979 and commercially introduced in 1981.
