First made available on June 24, 2010, the iPhone 4G initially priced out at $199 for a 16 GB model and $299 for a 32 GB model with a 2-year contract through AT&T. This model of the iPhone is known for its durability and high quality display. It boasts dual cameras and mics for improved quality and functionality.
Exterior Casing and Screen
At 9.3 millimeters thin, Apple claims the iPhone 4G to be the world's thinnest smart phone as of late 2010. The aluminosilicate glass exterior, which is the same material used for helicopter and high-speed train windshields, makes the iPhone 4G more durable and scratch resistant.
The 4.3 inch retinal display is 326 ppi (pixels per inch) with pixels so small that the naked eye cannot see individual pixels. This makes the iPhone 4G display the highest resolution smart phone screen in existence. According to Digital trends, this is four times the pixel density of the average LCD screen. The display is one of the larger screens on the smart phone market at 960 by 640 pixels.
The iPhone 4G's capacitive touch allows for multi-touch activities. This allows for features such as pinch to zoom and two-finger tap.
Hardware Specifications
The 5-megapixel camera has a backside-illuminated sensor designed to improve photo lighting by capturing more light in the sensor. The video feature also records HD videos at a 720 pixel resolution and captures 30 frames per second. The camera also allows for video chat. There is also a front-facing secondary camera built in.
The iPhone 4G has two microphones to enhance call quality. Next to the doc connector on the bottom of the phone is the main mic, used for phone calls, voice commands and audio memos. The second mic is located near the headphone jack on the top of the device; it is for face time calls and to help eliminate background noise during phone calls.
The iPhone's built-in rechargeable lithium-ion battery charges via USB to computer or through a power adapter. It allows for up to 7 hours of talk time or 300 minutes on standby. It runs an Apple A4 chip processor and has a 32 GB or 16 GB flash drive capacity.
Software
The iPhone 4G runs iOS 4 operating system, designed as the peer of the Android 2.1 operating system. The phone also includes a highly detailed photo and video editing software package. Software updates are available to improve the reception issues and other small operation issues. The advanced operating system allows users to sort applications into folders and allows for Web browsing via Safari browser.
