The iPhone 4 is a smartphone that was designed and marketed by Apple Inc. It is the fourth generation of the iPhone lineup, succeeding the iPhone 3GS and preceding the 4S. Following a number of notable leaks, the iPhone 4 was first unveiled on June 7, 2010, at Apple"s Worldwide Developers Conference in San Francisco,United States, United Kingdom, France, Germany, and Japan. The iPhone 4 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 time; it consisted of a stainless steel frame which doubled as an antenna, with internal components situated between two panels of aluminosilicate glass.Retina Display" (with a pixel density of 326 pixels per inch), while maintaining the same physical size and aspect ratio as its precursors, Apple"s A4 system-on-chip, along with iOS 4—which notably introduced multitasking functionality and app folders. It was the first iPhone at the time to include a front-facing camera, which made possible Apple"s new FaceTime video chat service, and the first to be released in a version for CDMA networks, ending AT&T"s period 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 powerful hardware, in comparison to previous models. While it was a market success (with over 600,000 pre-orders within 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 way. Most direct contact with the phone"s outer edge would cause a significant decrease in signal strength. Apple released iOS 4.0.1 to try to fix these issues, but were unsuccessful.

The iPhone 4 spent the longest time as Apple"s flagship iPhone model at fifteen months. Although the succeeding 4S was announced in October 2011, the 4 continued to be sold as a midrange model until September 2012, and thereafter as the entry-level offering in Apple"s lineup until September 2013 with the announcement of the iPhone 5S and iPhone 5C. The iPhone 4 had one of the longest lifespans of any iPhone ever produced, spanning close to four years and available in some developing countries until early 2015.

Before the official unveiling of the iPhone 4 on June 7, 2010, two prototypes were brought to the attention of the media, breaching Apple"s normally secretive development process. Many of the speculations regarding technical specifications proved accurate.

On April 19, 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.

On April 23, officers from the Rapid Enforcement Allied Computer Team (REACT) task force 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.Electronic Frontier Foundation criticized the raid as violating journalist source protection laws that forbid the seizure of journalist computers, as well as the suspicion that Apple had used its influence as a member of the steering committee, which is charged with direction and oversight of the California REACT task force to push police into action in a way 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.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 applicable, and cautioned that no charges have been issued at this point.

Pictures and video of a second prototype were published on a Vietnamese website, Taoviet, on May 12, 2010.DigiTimes reported that the screen resolution of the new phone was 960-by-640, which was confirmed by Apple at the iPhone 4"s official announcement.

The iPhone 4 was available for pre-order on June 15, 2010.Apple Stores which crashed due to the surge in traffic.AT&T and SoftBank, Apple"s exclusive partners in the United States and Japan respectively, who suspended advance sales of the iPhone 4 as demand threatened to exceed supply.

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 point.UTC, all iPhone 4 pre-order suppliers had sold out.

The iPhone 4 was also released through Orange in Tunisia and was available in eight cities at the launch.KT on September 10. In Israel, it was released, too, on September 24, through Cellcom, Pelephone and Orange. It was launched in Thailand on September 23 by AIS, DTAC and True Move, 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 limited quantities.Hanoi, Ho Chi Minh City and Da Nang, and then all over the country by the end of October.

On January 11, 2011, Verizon Wireless announced during a media event that it had reached an agreement with Apple and would begin selling a CDMA iPhone 4 in the United States, ending Apple"s exclusivity agreement with AT&T. The Verizon iPhone went on sale on February 10 and pre orders began on February 3.hotspot, with up to five devices connecting at one time. The February 3, 2011, presale of the iPhone 4 broke Verizon"s first day sales records for a single device.

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.

During Apple"s official unveiling of the iPhone 4S on October 4, 2011, it was announced that Sprint would begin carrying the reconfigured CDMA iPhone 4 and the iPhone 4S in the US on October 14.

In September 2013, after the release of the iPhone 5S and iPhone 5C, Apple stopped selling the iPhone 4 in most of their stores as well as on their website. It was replaced by the 8 GB iPhone 4S.

The display of the iPhone 4 was manufactured by LG under an exclusive contract with Apple. It features an LED backlit TFT LCD capacitive touchscreen with a pixel density of 326 pixels per inch (ppi) on a 3.5 in (8.9 cm) (diagonally measured), 960×640 display. Each pixel is 78 micrometers in width. The display has a contrast ratio of 800:1. The screen was marketed by Apple as 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 pixelretina can perceive.

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

However, Phil Plait, author of NASA regarding the camera on the Hubble Space Telescope, responded to the criticism by stating that "if you have [better than 20/20] eyesight, then at one foot away the iPhone 4"s pixels are resolved. The picture will look pixellated. If you have average eyesight, the picture will look just fine".

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

The iPhone 4 features an additional front-facing VGA camera, and a backside-illuminated 5 megapixel rear-facing camera with a 3.85 mm f/2.8 lens[1] and an LED flash. The rear-facing 5-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.digital zoom.

In contrast to Steve Jobs" announcement at WWDC 2010, recent Federal Communications Commission documentation showed that, in fact, the iPhone 4 contains a penta-band 3G UMTS antenna, not a quad-band 3G UMTS radio, as advertised by Apple. According to the FCC documentation filed by Apple, the radio inside the iPhone 4 supports 800, 850, 900, 1,900, and 2,100 MHz. The 800 MHz frequency, which is most commonly used in Japanese mobile phones, is not advertised as being supported by Apple.Skyworks SolutionsInfineon for GSM version.

The iPhone 4 is the first generation of iPhone to have a second microphone used for noise cancellation. It is located on the top of the unit near the headphone jack; the main microphone is on the bottom left.

The iPhone 4 introduces a gyroscopic sensor that detects 3-axis angular acceleration around the X, Y, and Z axes, enabling precise calculation of yaw, pitch, and roll. The gyroscope complements the accelerometer, a sensor that has been present since the original iPhone, which detects the device"s acceleration, shake, vibration shock, or fall by detecting linear acceleration along with one of three axes (X, Y, and Z). The combined data from the accelerometer and the gyroscope provides detailed and precise information about the device"s 6-axis movement in space. The 3 axes of the gyroscope combined with the 3 axes of the accelerometer enable the device to recognize approximately how far, fast, and in which direction it has moved in space.

The iPhone 4 is powered by the Apple A4 chip, which was designed by IntrinsitySamsung.system-on-a-chip is composed of an ARM Cortex-A8 CPU integrated with a PowerVR SGX535 GPU.first-generation iPad (released in 2010), where it was clocked at its rated speed of 1 GHz. The Apple A4 was the first ever CPU designed by 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 4 has 512 MB of DRAM. The additional DRAM supports increased performance and multi-tasking.flash memory, 8, 16 or 32 GB, and not on the SIM. Unlike prior generations, the storage capacity is not printed on the back of the unit.

The iPhone 4 uses a micro-SIM card 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 not be available for all networks globally. As a technical workaround, it is possible to trim a mini-SIM card with a knife or scissors so that it fits into the micro-SIM tray.

The iPhone 4 features a redesigned structure, designed by Jony Ive, a design that would later be reused and adapted for the iPhone 4S, 5, 5S and first-generation iPhone SE. Most notably, the bulges of the back panel as well as the band between the front and back are gone and have 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 have been reduced from their predecessor.

It is 115 millimetres (4.5 in) high, 58.6 millimetres (2.31 in) wide, and 9.4 millimetres (0.37 in) deep, compared to the iPhone 3GS, which is 116 millimetres (4.6 in) high, 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."

The iPhone 4 is structured around a stainless steel frame that wraps around the edge of the phone, acting both as the primary structure for the device and as the iPhone 4"s antennas. This metal band features two slits on the GSM version of the phone, one at the lower left, and one at the top (and a fake slit along the lower right, to cosmetically mirror the one at the lower left) that divide the band into two antenna sections: the left section of the band serves as the Bluetooth, Wi-Fi, and GPS antenna, and the right and lower sections of the band act as the antenna for GSM and UMTS connectivity.

The internal components are situated between two panels of aluminosilicate glass, described by Apple as being "chemically strengthened to be 20 times stiffer and 30 times harder than plastic," theoretically allowing it to be more scratch-resistant and durable than the prior models.

The iPhone 4 shipped with iOS 4, which was the newest version of Apple"s iOS mobile operating system at the time. iOS 4 introduced a multitasking system, allowing apps to remain "suspended" in memory, perform certain operations in the background, and allowing users to switch between apps using an on-screen menu.FaceTime, which allows users to perform video calls between other iPhone, iPad, iPod Touch, and OS X users.

The iPhone 4 supports up to iOS 7, 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-turn navigation, AirDrop, AirPlay mirroring, live camera filters, panorama mode and certain visual effects introduced by iOS 7, such as the blurring of translucent interface elements, the parallax effect on the home screen, and live wallpapers.

Apple updated the bumper with a wider volume switch hole with the release of the iPhone 4 for CDMA networks. The updated bumper is also compatible with iPhone 4S, the next-generation iPhone that has the same exterior design and measurements as the CDMA model of the iPhone 4, but with a SIM card slot as well.

CNET reacted to the announcement by explaining how it believes that iMovie for iOS was the "most exciting part of this year"s WWDC Keynote". The article noted how the iPhone 4, unlike current cameras, can record HD content and then edit it from the same device, labeling it a "true mobile editing suite".

Reviews of the iPhone 4 were largely positive. Walt Mossberg of Engadget named it the "best smartphone on the market" in June 2010.CNET gave the iPhone 4 a rating of 8.6 out of 10, one of the highest ratings it had given any smartphone.TechRadar gave the device 4.5/5 stars.

Shortly after the iPhone 4 was launched, some consumers reported that signal strength of the phone was reduced when touching the lower left edge of the phone, bridging one of the two locations which separates the two antennas, resulting in dropped calls in some areas with lower signal reception.

As a consequence of this problem, it was reported on July 2, 2010 that several iPhone 4 users were planning on suing Apple and AT&T for fraud by concealment, negligence, intentional misrepresentation and defective design. The legal challenge was started by a law firm, who set up a website to recruit disenchanted iPhone 4 buyers for a lawsuit against Apple.

Apple explained how the formula it used to calculate the number of bars to display 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.

On July 16, 2010, at a press conference which included a private tour of Apple"s antenna design lab for journalists,Steve Jobs announced 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 free case offer would be valid until September 30, 2010, when Apple would re-evaluate the situation.AppleCare which showed that only 0.55 percent of all iPhone 4 users have complained to the company about the issue, while the number of phones returned to Apple was 1.7 percent – 4.3 percentage points less than the number of iPhone 3GS models that were returned in the first month of the phone"s launch.

Despite the negative media attention 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 by ChangeWave Research.

In 2011, two iPhone 4 units equipped with a special application were taken to the International Space Station aboard the Space Shuttle on the STS-135 mission.

Apple"s OEM suppliers won"t sell iphone parts to anybody but Apple Inc. But in China some apple sales agencies want to earn more money. They will sell Apple products in 2 ways: one is selling them with quality guarantee in higher prices, the other is selling them without any quality guarantee in lower prices(trust me, there are still many customer want to buy iphone this way with cheaper price in China). In the case of the second ways of selling iphones, they will replace some major iphone parts before selling. Normally they will replace iphone LCD screen assembly, iphone battery, iphone back cover, iphone dock connector cable with cheaper copy ones. And they will sell out these original iphone parts to someone else to earn money. Now if you take a wild guess you maybe understand why we can offer our customers original iphone parts.
