iPhone 4 – 32 GB


The iPhone 4 has a 3.5″ 960 by 640 (326 ppi) “Retina display” (Apple has given the display this name because 326 ppi is said to be beyond the 300 ppi distinguishable by the human eye). It is LED-backlit, uses IPS (In-Plane Switching) technology, has an 800:1 typical contrast ratio and is coated with a fingerprint-resistant “oleophobic” (oil repellent) coating. The back of the phone, which also is made of glass, has an oleophobic coating as well.

The iPhone 4, heralded as the “biggest leap since the original iPhone,” uses an all stainless steel body design with an ultra high-density 3.5-inch, IPS, LED-backlit 960×640 326 ppi multi-touch “retina” display, mobile and data antennas integrated in the “metal band” that wraps around the sides of the phone, and a chemically hardened “aluminosilcate” glass front over both the display and a black frame and the chemically hardened black glass backas well (it was introduced with a white option on June 7, 2010, too, but this version did not ship until April 28, 2011). Regardless of color, both the front and back have an “oleophobic” oil repellent coating.

It has dual cameras — a 5 megapixel HD video/still camera (720p at 30 FPS) with a “backside illuminated sensor,” a 5X digital zoom, and an LED flash on the rear and a VGA quality video/still camera on the front designed for video conferencing over a Wi-Fi network with Apple’s included “FaceTime” application. It has dual noise-cancelling microphones also.

It is powered by an “Apple A4” processor of unspecified speed, has 512 MB of RAM, and has 8 GB, 16 GB, or 32 GB of internal storage (8 GB configuration introduced October 4, 2011). Network support includes UMTS/HSDPA/HSUPA (850, 900, 1900, 2100 MHz) and GSM/EDGE (850, 900, 1800, 1900 MHz). 802.11g/n and Bluetooth 2.1+EDR are supported as well.

Like the iPhone 3GS that came before it, the iPhone 4 includes a digital compass, A-GPS, and an accelerometer, but adds a 3-axis gyroscope to its list of sensors for additional 3D gaming options.

Apple reports that the iPhone 4 provides “up to” 40 hours of audio playback, 14 hours of talk time on 2G, 7 hours of talk time on 3G, 6 hours of Internet use on 3G, 10 hours of Internet use on Wi-Fi, 10 hours of video playback and 300 hours of standby time.

In the US, for new/qualified AT&T Wireless customers, the 16 GB configuration originally was US$199 and the 32 GB configuration originally was US$299 with a two year contract. Starting June 14, 2011, in the US, Apple also began offering this iPhone 4 unlocked in white or black for US$649 with 16 GB of storage and US$749 with 32 GB of storage (and discontinued these options on October 4, 2011).

On October 4, 2011, Apple introduced a lower-end 8 GB configuration for US$99 subsidized by a two-year AT&T contract and also made this configuration available unlocked in the US for US$549 (and discontinued this option on September 12, 2012).

Finally, on September 12, 2012, Apple dropped the price of the 8 GB iPhone 4 (GSM) model to US$0 with a two-year contract or US$450 unlocked and contract-free. It was discontinued on September 10, 2013, with the exception of mainland China, where it remained available for RMB 2,588 until September 9, 2014.
