The iPhone 4 is the 4th generation of Apple’s famous smartphone. It is described as having introduced the most changes since the release of the original iPhone. Just as its predecessors, it combines the functions of a mobile phone, an iPod, Internet communications and many others. Compared to the iPhone’s previous generations, the 4th generation is presented with a sleeker, more angular design. Besides the differences in the iPhone’s external characteristics, it introduces new features, such as an additional front-facing VGA camera, additional DRAM supports – due to which an increased performance and multi-tasking are possible, and an Apple A4 processor, just to mention a few.

- Before the official unveiling of the iPhone 4 on June 7, 2010, Apple brought two prototypes to the attention of the media, breaching the company’s secretive development process. For example, on January 27, 2010, the website Engadget received leaked images of an unreleased iPad, and unbeknownst to the editors and readers these images contained two of the iPhone 4! It was not until the subsequent Gizmodo release (see below) were they aware of the complete contents of the images. It resulted that most of the speculations regarding technical specifications proved accurate.
- On April 19, 2010, the website Gizmodo reported that the site had purchased an iPhone prototype for $5000, and furthermore, had conducted a product teardown of the device. The prototype is reported to have been lost by an Apple employee, Gray Powell, in Redwood City, California. Shortly after Gizmodo published detailed information about the prototype, Apple’s legal associates formally requested for the device to be returned to Apple. Gizmodo responded immediately with the intent to cooperate. On April 23 2010, officers from the REACT (short for Rapid Enforcement Allied Computer Team) 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. The Electronic Frontier Foundation reacted criticizing the raid as an action which violated journalist source protection laws that forbid the seizure of journalist computers. The foundation expressed 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. The District Attorney has stated that the investigation has been 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 iPhone 4 prototype were published on a Vietnamese website, Taoviet, on May 12, 2010. The second prototype was almost identical to the first. It used an A4 chip manufactured by Apple. Taoviet website purchased the prototype for $4,000. DigiTimes reported that the screen resolution of the new phone was 960-by-640, which was later confirmed by Apple at the iPhone 4’s official announcement.
- Users praised the revamped design of the iPhone 4, as well as its powerful hardware in comparison to previous models. Over 600,000 pre-orders were placed within 24 hours from the release of this smartphone.
- The iPhone 4 received positive reception from many sources, with critics praising its revamped design and more powerful hardware in comparison to previous iPhone’s models.
- There were reports that abnormalities in antenna design caused the iPhone 4 to lose its cellular signal if held in the most natural way. According to the same reports, most human contact with the phone’s outer edge would cause a significant decrease in signal strength.
- This model was succeeded as Apple’s flagship smartphone in 2011 by the iPhone 4S. However, iPhone 4 continued to be produced until 2013. This smartphone had the longest lifespan of any iPhone ever produced, spanning close to four years and available in some countries until early 2014.
- The Revision A model of the iPhone 4 was first introduced at a price of US$99 with a two-year AT&T contract. However, the price was later dropped to US$0 subsidized by a two-year contract.
