iPhone 2G

The first generation iPhone was Apple’s first handheld device that combined mobile phone, iPod and internet into one platform. These GSM Quad-band phones operate on 850, 900, 1800 and 1900 MHz frequencies and sport a 3.5” display with 320x480 resolution at 163ppi. The first generation iPhones where available in 4GB, 8GB or 16GB of configurations with 128MB standard RAM. Built in Wi-Fi 802.11b/g, EDGE and Bluetooth 2.0 provide multiple connectivity options. A 2.0 megapixel camera integrated into the 4 ounce .46” thick aluminum casing made this a highly demanded phone.

Apple initially estimated the Lithium Ion battery provided up to 16 hours of audio playback and up to 5 hours of talk, video, and browsing but on June 18, 2007, Apple increased those times to up to 8 hours talk time, 24 hours audio playback, 7 hours of video playback, and 6 hours web browsing. It also features up to 250 hours standby time. The multi-touch screen allows the user to control all functions with one or more fingers on the optical quality glass display. Also included is an accelerometor that enables the device to detect whether it is being held in portrait or landscape mode. An ambient light sensor adjusts the screens brightness according to lighting conditions and proximity sensor disables the display when the phone is held to the ear.

The iPhone 3G is similar to the first generation iPhone but is also able to connect to the 3G (850, 1900, 2100 MHz 3.6 Mbps) network and is GPS enabled. Apple used the same 3.5” display with 320x480 resolution at 163 ppi, but the new back consists of either a black or white plastic cover. This cover added 0.02 of an inch to the entire phone. 8GB or 16GB configurations are available with 128MB onboard RAM.
