iPhone 4
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.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.[12] 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.[15] The 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.[16] 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 applicable, and cautioned that no charges have been issued at this point.[23] The same issue was reported with 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.[37] 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.Among the most popular rumours are those concerning the phone's internal camera being adversely affected by light leaking in due to the semi-translucent glass and the white paint.[39][40] Other sources report that the problem relates to Apple's inability to match the white colour of the front faceplate with that of the home button.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.[52] However, Phil Plait, author of Bad Astronomy, whose career includes a collaboration with 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.[59] 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.Due to the relatively aged hardware of the iPhone 4, most 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.[74] Rhodri Marsden of The Independent said that "aside from the introduction of face-to-face video calling, it's not a staggering feature set," instead focusing on how the device is "more powerful than its predecessor, speedier, easier to use and will make previously laborious tasks seem like a cinch".[75] 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".[86][87][88] In response, Apple issued a statement advising that customers should "avoid gripping [the phone] in the lower left corner" when making or receiving a call.[90] 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 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.[95] The magazine rejected Apple's explanation after conducting tests in a controlled environment, and comparing the results against prior generations of iPhone.[81] The magazine also tested the iPhone 4 while it was wearing a Bumper, a frame-like cover sold by Apple that prevents direct contact with the antenna, reporting that it did resolve the problem.[96] 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.Jobs also announced that Apple could not produce enough Bumpers for all owners of the phone, but would source a supply and offer a range of cases.[102] However, because Jobs did not specify a time line for fixing the problem, and the offering for a free bumper only being a temporary solution, PC World decided to remove the iPhone 4 from its "Top 10 Cell Phones" chart and reassign it to a pending rating.
