The
iPhone 4
is a smartphone that was designed and marketed by Apple tree Inc. Information technology is the fourth generation of the iPhone lineup, succeeding the iPhone 3GS and preceding the 4S. Post-obit a number of notable leaks, the iPhone 4 was commencement unveiled on June 7, 2010, at Apple’s Worldwide Developers Conference in San Francisco,[9]
and was released on June 24, 2010, in the United States, United Kingdom, French republic, Germany, and Japan. The iPhone four introduced a new hardware design to the iPhone family, which Apple’s CEO Steve Jobs touted as the thinnest smartphone in the world at the fourth dimension; it consisted of a stainless steel frame which doubled as an antenna, with internal components situated betwixt two panels of aluminosilicate glass.[10]
The iPhone 4 introduced Apple’s new high-resolution “Retina Display” (with a pixel density of 326 pixels per inch), while maintaining the same concrete size and attribute ratio as its precursors, Apple’southward A4 organisation-on-chip, along with iOS 4—which notably introduced multitasking functionality and Apple’s new FaceTime video conversation service. It was the get-go iPhone at the time to include a front-facing camera, and the first to be released in a version for CDMA networks, ending AT&T’s menstruum as the exclusive carrier of iPhone products in the United States.

The iPhone 4 received a largely positive reception, with critics praising its revamped design and more than powerful hardware, in comparison to previous models. While it was a market success (with over 600,000 pre-orders inside 24 hours), the release of the iPhone 4 was plagued by highly publicized reports concerning abnormalities in its new antenna design that caused the device to lose its cellular signal if held in a certain style. Nigh directly contact with the phone’south outer border would crusade a significant decrease in signal strength. Apple released iOS 4.0.1 to endeavour to fix these problems, but were unsuccessful.[11]

The iPhone 4 spent the longest fourth dimension equally Apple tree’due south flagship iPhone model at fifteen months. Although the succeeding 4S was announced in Oct 2011, the four continued to be sold every bit a midrange model until September 2012, and thereafter as the entry-level offering in Apple tree’s lineup until September 2013 with the announcement of the iPhone 5S/iPhone 5C. The iPhone 4 had one of the longest lifespans of whatsoever iPhone ever produced, spanning shut to iv years and available in some developing countries until early on 2015.

History

[edit]

Prototypes

[edit]

Before the official unveiling of the iPhone 4 on June seven, 2010, ii prototypes were brought to the attending of the media, breaching Apple’southward normally secretive development process. Many of the speculations regarding technical specifications proved authentic.

Engadget leak

[edit]

On January 27, 2010, gadget website Engadget received leaked images of the unreleased first-generation iPad.[12]
Unbeknownst to the editors and readers, these images contained 2 unreleased iPhone 4 models.[13]
Information technology wasn’t until the subsequent Gizmodo release that they were enlightened of the complete contents of the images.[14]

Gizmodo leak

[edit]

On Apr xix, 2010, gadget website Gizmodo reported that they had purchased an iPhone prototype for $5000, and furthermore, had conducted a product teardown of the device. The prototype was reported to have been lost by an Apple employee, Gray Powell, in Redwood City, California.[xv]
Before long after Gizmodo published detailed data about the prototype, Apple’south legal associates formally requested for the phone to exist returned to Apple tree, and Gizmodo responded with the intent to cooperate.[sixteen]

On April 23, officers from the Rapid Enforcement Centrolineal Reckoner Team (REACT) chore forcefulness of the California HTTAP Program raided the home of Jason Chen, the Gizmodo editor responsible for reviewing the prototype, seizing all of his computers and hard drives.[17]
The Electronic Frontier Foundation criticized the raid equally violating announcer source protection laws that forbid the seizure of announcer computers, as well every bit the suspicion that Apple had used its influence every bit a fellow member of the steering commission, which is charged with direction and oversight of the California REACT task forcefulness to push constabulary into activity in a fashion that would not normally be conducted for this type of incident. Apple had already received the iPhone prototype before the raid when it was returned by Gizmodo.[18]
The District Attorney stated that the investigation was suspended, and discontinued searching through the Gizmodo editor’s belongings as they determine whether the shield laws are applicative, and cautioned that no charges accept been issued at this point.[xix]
[20]

Taoviet leak

[edit]

Pictures and video of a second prototype were published on a Vietnamese website, Taoviet, on May 12, 2010.[21]
It was almost identical to the first, and used an A4 flake manufactured by Apple tree.[22]
The website purchased the paradigm for $four,000.[23]
DigiTimes reported that the screen resolution of the new phone was 960-by-640, which was confirmed by Apple at the iPhone iv’s official annunciation.

Release

[edit]

The iPhone 4 was available for pre-order on June 15, 2010.[24]
Customers attempting to pre-order the iPhone 4 reported problems with the pre-society process on the The states and UK online Apple Stores which crashed due to the surge in traffic.[25]
The aforementioned issue was reported with AT&T and SoftBank, Apple tree’southward exclusive partners in the United states and Nihon respectively, who suspended advance sales of the iPhone iv as demand threatened to exceed supply.[26]
Retail stores were also unable to consummate pre-lodge transactions due to the servers crashing.[27]

Apple and its partner carriers received 600,000 pre-orders for the iPhone 4 in the first 24 hours, the largest number of pre-orders Apple had received in a single day for any device up to that bespeak.[28]
Engadget
reported that at xx:thirty UTC, all iPhone 4 pre-guild suppliers had sold out.[29]
i.7 million iPhone iv models were sold in its showtime three days of availability.[thirty]

The iPhone 4 was also released through Orange in Tunisia and was available in viii cities at the launch.[31]
On July 30, 2010, iPhone 4 was made available for sale in Australia, New Zealand and 15 other countries with free bumper cases.[32]
[33]
In Republic of korea, it was released by KT on September 10. In Israel, it was released, too, on September 24, through Cellcom, Pelephone and Orangish. It was launched in Thailand on September 23 by AIS, DTAC and True Motion, and in Malaysia on September 26 in Kuala Lumpur, and nationwide on September 27 according to the website of Maxis.

The iPhone 4 was released in South Africa on September 22 on the Vodacom and MTN networks, in very express quantities.[34]
The iPhone 4 was launched in Vietnam on September xxx on VinaPhone and Viettel, at first in 3 major cities: Hanoi, Ho Chi Minh city and Da Nang, and so all over the country past the end of October.[35]
[36]

The iPhone 4 was launched in India on May 27, 2011 by Aircel and Airtel.[37]

On January 11, 2011, Verizon Wireless appear during a media consequence that it had reached an agreement with Apple tree and would begin selling a CDMA iPhone 4 in the United states of america, catastrophe Apple tree’s exclusivity agreement with AT&T. The Verizon iPhone went on auction on February 10 and pre orders began on February three.[38]
[39]
[xl]
The Verizon iPhone includes the ‘Personal Hotspot” feature which allows a user to use the iPhone as a wireless hotspot, with up to five devices connecting at 1 time. The Feb 3, 2011, presale of the iPhone 4 broke Verizon’due south first day sales records for a single device.[41]

On June 24, 2010, Apple stated that the white iPhone 4 models were proving more “challenging to manufacture” than expected, and initially pushed the release date back to the second half of July. There was a lot of speculation surrounding the filibuster of the white iPhone four. Among the most popular rumours are those concerning the phone’south internal camera being adversely affected by lite leaking in due to the semi-translucent glass and the white paint. Other sources report that the problem relates to Apple’southward inability to lucifer the white colour of the forepart faceplate with that of the home button.[42]

On April 27, 2011, Apple announced that it would be releasing the white iPhone 4 model on Apr 28, 2011, for both GSM and CDMA.[43]
The release of the white iPhone 4 was carried out on April 28.[44]
[45]

During Apple tree’s official unveiling of the iPhone 4S on Oct four, 2011, it was announced that Dart would begin conveying the reconfigured CDMA iPhone 4 and the iPhone 4S in the US on October 14.[46]
[47]

Discontinuation

[edit]

In September 2013, later on the release of the iPhone 5S and iPhone 5C, Apple stopped selling the iPhone four in most of their stores also as on their website. It was replaced by the 8 GB iPhone 4S.[48]
[49]

Hardware

[edit]

Brandish

[edit]

The display of the iPhone four was manufactured by LG under an sectional contract with Apple. It features an LED backlit TFT LCD capacitive touchscreen with a pixel density of 326 pixels per inch (ppi) on a iii.5 in (8.9 cm) (diagonally measured), 960×640 brandish. Each pixel is 78 micrometers in width. The display has a contrast ratio of 800:1. The screen was marketed by Apple equally the “Retina display”, based on the assertion that a display of approximately 300 ppi at a distance of 305 millimetres (12 in) from one’s eye, or 57 arcseconds per pixel[51]
is the maximum corporeality of detail that the human retina can perceive.[52]
With the iPhone expected to be used at a distance of nearly 12 inches from the eyes, a college resolution would allegedly have no effect on the epitome’s apparent quality as the maximum potential of the human eye has already been met.

This claim was widely disputed. Raymond Soneira, president of DisplayMate Technologies, said in an interview with the
Wired
mag, that his claims by Jobs are something of an exaggeration: “It is reasonably close to existence a perfect display, but Steve pushed information technology a little too far”. Soneira stated that the resolution of the human retina is higher than claimed past Apple tree, working out to 477 PPI at 12 inches (305 mm) from the optics, or 36 arcseconds per pixel.[53]

All the same, Phil Plait, author of
Bad Astronomy, whose career includes a collaboration with NASA regarding the photographic camera on the Hubble Space Telescope, responded to the criticism by stating that “if y’all have [better than 20/20] eyesight, and then at one foot away the iPhone 4’southward pixels are resolved. The picture will look pixellated. If you have average eyesight, the flick will look just fine”.[54]
[55]

Photographic camera

[edit]

The iPhone 4 is the first iPhone model to take two cameras. The LED flash for the rear-facing photographic camera (top) and the forward-facing photographic camera (bottom, left of the speaker) are not nowadays in older models.

The iPhone 4 features an additional front-facing VGA camera, and a behind-illuminated 5 megapixel rear-facing camera with a three.85 mm f/ii.8 lens[56][1] and an LED flash. The rear-facing v-megapixel camera is capable of recording HD video in 720p at 30 frames per second. Both cameras make use of the
tap to focus
feature, part of iOS 4, for photo and video recording.[57]
The rear-facing camera has a five× digital zoom.

Connectivity

[edit]

In contrast to Steve Jobs’ proclamation at WWDC 2010, recent Federal Communications Committee documentation showed that, in fact, the iPhone four contains a penta-ring 3G UMTS antenna, non a quad-band 3G UMTS radio, as advertised by Apple. According to the FCC documentation filed past Apple, the radio within the iPhone 4 supports 800, 850, 900, 1,900, and 2,100 MHz. The 800 MHz frequency, which is virtually normally used in Japanese mobile phones, is not advertised every bit existence supported by Apple.[58]
However, the 800 MHz band is a subset of the 850 MHz band, which probably explains why the device was advertised as quad-band.[

The chip-sets were manufactured by Skyworks Solutions[59]
and Infineon for GSM version.

As with almost of Apple’due south mobile products at the fourth dimension, the iPhone 4 likewise used the 30 pin dock connector equally its simply external data port.

The iPhone 4 is the first generation of iPhone to have a 2d microphone used for noise counterfoil. It is located on the peak of the unit near the headphone jack; the main microphone is on the lesser left.[60]

Gyroscope and accelerometer

[edit]

The iPhone 4 introduces a gyroscopic sensor that detects 3-axis angular acceleration effectually the X, Y, and Z axes, enabling precise calculation of yaw, pitch, and curl. The gyroscope complements the accelerometer, a sensor that has been present since the original iPhone, which detects the device’s dispatch, shake, vibration shock, or autumn by detecting linear acceleration along with one of 3 axes (X, Y, and Z). The combined information from the accelerometer and the gyroscope provides detailed and precise information almost the device’south six-axis movement in space. The 3 axes of the gyroscope combined with the iii axes of the accelerometer enable the device to recognize approximately how far, fast, and in which direction it has moved in space.[61]


Processor, retention and storage

[edit]

Apple A4 flake used in the iPhone 4

The iPhone 4 is powered by the Apple A4 flake, which was designed by Intrinsity[62]
and, similar all prior iPhone models, manufactured by Samsung.[63]
This system-on-a-chip is composed of an ARM Cortex-A8 CPU integrated with a PowerVR SGX535 GPU.[64]
The Apple tree A4 was also used in the offset-generation iPad (released in 2010), where it was clocked at its rated speed of 1 GHz. The Apple tree A4 was the get-go ever CPU designed past Apple. The clock speed in the iPhone 4 was never disclosed. All prior models of the iPhone had underclocked the CPU, which typically extends battery life and lowers heat dissipation.

The iPhone four has 512 MB of DRAM. The additional DRAM supports increased performance and multi-tasking.[65]
As on prior models, all data is stored in flash memory, eight, 16 or 32 GB, and not on the SIM. Unlike prior generations, the storage capacity is non printed on the back of the unit.

Micro-SIM

[edit]

The iPhone iv uses a micro-SIM carte du jour on iPhone 4 devices running on a GSM network, which is positioned in an ejectable tray, located on the right side of the device. On a CDMA network, however, the phone connects to the network using an ESN. All prior models have used regular mini-SIM cards. Depending on the operator, micro-SIM cards may non be bachelor for all networks globally. As a technical workaround, it is possible to trim a mini-SIM card with a knife or scissors so that information technology fits into the micro-SIM tray.[66]

Design

[edit]

The iPhone iv is constructed of glass faces and a metal rim.

The iPhone 4 features a redesigned structure, designed by Jony Ive, a pattern that would later on be reused and adjusted for the iPhone 4S, 5, 5S and get-go-generation iPhone SE. Most notably, the bulges of the back panel as well as the band between the forepart and dorsum are gone and take been replaced with flattened surfaces. The redesign reflects the utilitarianism and uniformity of existing Apple products, such as the iPad and the iMac. The overall dimensions of the iPhone 4 accept been reduced from their predecessor.[67]

It is 115 millimetres (four.5 in) loftier, 58.6 millimetres (2.31 in) wide, and 9.4 millimetres (0.37 in) deep, compared to the iPhone 3GS, which is 116 millimetres (4.vi in) loftier, 62 millimetres (2.4 in) wide, and 12 millimetres (0.47 in) deep; making the iPhone 4 24% thinner than its predecessor, the iPhone 3GS. Steve Jobs claimed it to be “the thinnest smartphone on the planet.”[67]
The reduced size of the device is primarily due to the externally placed antenna.

The iPhone four is structured around a stainless steel frame that wraps around the edge of the telephone, acting both as the chief construction for the device and equally the iPhone 4’s antennas. This metal band features ii slits on the GSM version of the phone, one at the lower left, and one at the peak (and a fake slit along the lower right, to cosmetically mirror the one at the lower left) that dissever the band into two antenna sections: the left department of the band serves as the Bluetooth, Wi-Fi, and GPS antenna, and the correct and lower sections of the ring human activity as the antenna for GSM and UMTS connectivity.

On the CDMA version of the phone, in that location are four slits in the metallic band. Ii at the top (on the left and correct) and two at the lesser. This divides the metal band into four different segments, which similar the GSM version of the phone, serve as different antennas for connectivity. The top portion of the band (divided by the top left and right slits) is for connecting to the CDMA network. The left portion of the metal band is for Bluetooth, Wi-Fi, and GPS just similar the GSM version. The right side is non an antenna but serves to cosmetically mirror the left side and also to create a similar look to the GSM version of the phone.

The internal components are situated between two panels of aluminosilicate glass, described by Apple every bit being “chemically strengthened to be 20 times stiffer and 30 times harder than plastic,” theoretically assuasive information technology to exist more scratch-resistant and durable than the prior models.[10]

In autumn 2010, pentalobe screws started to replace the Philips screws used in postal service-repair units in the United states of america and in production units in Japan.[68]

Software

[edit]

The iPhone 4 shipped with iOS four, which was the newest version of Apple tree’southward iOS mobile operating organization at the time. iOS iv introduced a multitasking organization, allowing apps to remain “suspended” in memory, perform certain operations in the background, and allowing users to switch between apps using an on-screen carte.[69]
It too introduced FaceTime, which allows users to perform video calls between other iPhone, iPad, iPod Affect, and Os X users.

The iPhone 4 supports upward to iOS seven, released in September 2013. Due to the relatively aged hardware of the iPhone 4, certain features available on newer iPhone models are not available on the device; as of iOS 7, they include Siri, 3D maps and turn-by-plow navigation, AirDrop, AirPlay mirroring, live photographic camera filters, panorama mode and certain visual effects introduced past iOS 7, such every bit the blurring of translucent interface elements, the parallax upshot on the home screen, and live wallpapers.[70]
While still subject to the same limitations, iOS 7.ane did bring some slight performance improvements to the operating system on the iPhone iv. iOS 7, specifically iOS vii.1.ii, is the last version of iOS to support the iPhone 4. Unlike the iPhone 4S, the iPhone 4 did not receive the iOS 8 update due to performance bug.[71]
[72]

Accessories

[edit]

Bumper

[edit]

An iPhone 4 Bumper is a ring of rubber and plastic that surrounds the edge of the iPhone 4, to protect the phone. The inner part is rubber with an external ring fabricated of plastic. The Bumper wraps around the edges of the device protecting the edges, and to a bottom extent, the screen. The Bumper does not cover the front or rear of the telephone, though it does slightly raise the iPhone off whatever surface it is sitting on.[73]

Additionally, the plastic band houses metal buttons for the volume controls and sleep/wake button. The 6 holes in the Bumper enable admission to the mute switch, dock connector, headphone jack, speaker, and microphones.[73]

Apple updated the bumper with a wider book switch hole with the release of the iPhone 4 for CDMA networks. The updated bumper is also uniform with iPhone 4S, the next-generation iPhone that has the same outside design and measurements as the CDMA model of the iPhone iv, but with a SIM carte du jour slot besides.

Reception

[edit]

Pre-release

[edit]

Pre-release reception was largely positive.[74]
The announcement included information that had not been covered by Gizmodo. Flim-flam News commented that “seeing information technology in action is far more than informative than staring at Gizmodo’southward photos of a busted test unit”.[75]
Rhodri Marsden of The Independent said that “aside from the introduction of contiguous video calling, it’s not a staggering feature set,” instead focusing on how the device is “more powerful than its predecessor, speedier, easier to utilize and will make previously laborious tasks seem similar a cinch”.[76]

CNET reacted to the annunciation by explaining how it believes that iMovie for iOS was the “virtually exciting role of this year’due south WWDC Keynote”. The article noted how the iPhone 4, different current cameras, tin can record Hard disk content and and then edit it from the same device, labeling it a “true mobile editing suite”.[77]

Reviews

[edit]

Reviews of the iPhone 4 were largely positive. Walt Mossberg of
The Wall Street Journal
called the device “the best device in its form”.[78]
Engadget named it the “best smartphone on the market” in June 2010.[79]
CNET gave the iPhone 4 a rating of 8.6 out of 10, one of the highest ratings it had given any smartphone.[fourscore]
TechRadar gave the device 4.v/5 stars.[81]
Consumer Reports said the betoken problem was the reason they did not rate it a “recommended” model, although the other tests ranked it highest among smart phones.[82]

Joshua Topolsky of Engadget described the device’south industrial pattern as being “more detailed and sophisticated” than its predecessor.[79]

Technical problems

[edit]

Some users reported a yellow discoloration of the screen that disappeared later on several days, which was attributed to the glass lamination gum that was used. It did non have time to dry fully earlier the unit of measurement reached consumers due to the speed of manufacturing.[83]
Another issue reported by some users within days of the iPhone 4 release was that during calls the proximity sensor can be insensitive, so that facial contact with the touchscreen tin end calls, mute calls, and punch other numbers.[84]
Some users reported that, specially in low-low-cal conditions, photos taken on the iPhone 4 sometimes contained blue or green “splotches.” Issues with white balance were too discovered, specially when using the wink.[85]
[86]

Antenna

[edit]

Shortly after the iPhone 4 was launched, some consumers reported that signal strength of the phone was reduced when touching the lower left border of the phone, bridging one of the ii locations which separates the two antennas, resulting in dropped calls in some areas with lower bespeak reception.[87]
[88]
[89]
In response, Apple issued a statement advising that customers should “avoid gripping [the phone] in the lower left corner” when making or receiving a phone call.[90]
Internally, senior antenna expert Ruben Caballero raised concerns to CEO Steve Jobs that the antenna blueprint could atomic number 82 to dropped calls.[91]

As a consequence of this problem, it was reported on July 2, 2010 that several iPhone 4 users were planning on suing Apple tree and AT&T for fraud by darkening, negligence, intentional misrepresentation and defective design. The legal challenge was started by a law firm, who gear up a website to recruit disenchanted iPhone iv buyers for a lawsuit against Apple.[92]
[93]
After that day, Apple issued another statement stating that it had discovered the crusade of the “dramatic drop in bars”.[94]

Apple tree explained how the formula it used to summate the number of bars to brandish was “totally wrong”. Apple promised to correct the issue and release a software update within a few weeks that would address the “mistake”, which had been present since the original iPhone.[94]
The New York Times
commented that “the failure to notice this longstanding problem earlier is astonishing.”[95]

Consumer Reports
initially stated that the iPhone 4’s signal bug are not “unique, and may not exist serious” and it continued to mention that betoken loss is a trouble that is faced by the entire smartphone industry. Information technology was such a trouble that Apple made a formal apology onstage. The adjacent day, the mag altered their stance after encountering instances of dropped calls.[96]
The magazine rejected Apple tree’south explanation after conducting tests in a controlled surroundings, and comparing the results against prior generations of iPhone. Information technology sarcastically pointed out that using a piece of record to cover the lower left antenna gap was one way to fix the problem, only recommended that consumers who “desire an iPhone that works well without a masking-record prepare” buy the iPhone 3GS instead.[82]
The magazine besides tested the iPhone iv while information technology was wearing a
Bumper, a frame-like cover sold past Apple that prevents directly contact with the antenna, reporting that information technology did resolve the problem.[97]
CNN
repeated
Consumer Reports’
statement that a small amount of duct tape had proven an effective fix to the iPhone 4’s dropped call issue.[98]

On July 16, 2010, at a press conference which included a private tour of Apple tree’south antenna design lab for journalists,[99]
Steve Jobs appear that Apple would provide all iPhone 4 owners with a free case to help solve the antenna issue and a refund to those users who had already purchased a Bumper. The complimentary case offer would be valid until September thirty, 2010, when Apple would re-evaluate the situation.[100]
[101]
To get a free case, owners were able to apply via an app installed on the phone institute in the App Store from July 22, 2010 to September 30, 2010. Jobs likewise announced that Apple could not produce enough Bumpers for all owners of the telephone, but would source a supply and offer a range of cases.[102]
Additionally, Jobs cited figures from AppleCare which showed that but 0.55 percentage of all iPhone iv users have complained to the visitor about the issue, while the number of phones returned to Apple was 1.7 percent – iv.3 percentage points less than the number of iPhone 3GS models that were returned in the first month of the phone’s launch.[102]

Consumer Reports
noted that the solution was not permanent, though a good offset step.[103]
However, considering Jobs did not specify a fourth dimension line for fixing the trouble, and the offering for a gratuitous bumper only being a temporary solution,
PC Earth
decided to remove the iPhone iv from its “Top ten Cell Phones” chart and reassign it to a pending rating.[104]

Despite the negative media attending regarding the antenna issues, 72% of iPhone 4 users say that they are “very satisfied” with their iPhone 4 according to an August 2010 survey past ChangeWave Enquiry.[105]
The iPhone 4 model continued to exist sold unchanged up until September 2013.

iPhones in space

[edit]

In 2011, two iPhone 4 units equipped with a special awarding were taken to the International Space Station aboard the Space Shuttle on the STS-135 mission.[106]
The devices were used in various experiments, utilizing sensors and a special app.[106]
