The Original iPhone

The iPhone, classified as a bar smartphone, is an Apple Inc. product that supports multimedia and Internet connectivity through its GSM connection or Wi-Fi. The phone’s input structure is limited to a full size touchscreen on the front and four other buttons located on the front, side and top of the design. The phone was originally released in 4 GB and 8 GB sizes. The unit, since it physically lacks a keyboard, uses an onscreen virtual keyboard to input data. Other notable features of the phone are its 2.0 megapixel camera, email, text messaging, video voicemail, iPod(turning the phone into a functioning version of a video iPod), internet surfing through Apple’s Safari web browser and access to third party applications through Apple’s App Store.

The iPhone was released in the United States on June 29, 2007(1). The phone was named as Time magazine’s Invention of the Year in 2007(2). The phone works on a quad-band GSM network that supports EDGE technology for internet connectivity. The iPhone OS, the phones operating system, was referred to as “OS X” until the release of the iPhone SDK (Software Developers Kit) on March 6, 2008 (3). It was then referred to as the iPhone OS. This operating system allows users to direct the functionality of the phone with gestures made by the touch of one’s fingertips. Gestures acknowledged by the operating system are swipes, taps, pinches and reverse pinches. These movements replace the common phone inputs such as a keyboard or trackball. The phone also supports input from its internal accelerometer. The other four buttons on the phone control the phones volume along the side; placing the phone in sleep mode on the top; and returning the phone to its home screen on the phone’s face. The phone’s operating system can be upgraded to the newest version of the system: iPhone OS 3.1.

The iPhone OS comes loaded with software on its home screen including: Phone, Mail, Safari, iPod, Camera, Photos, YouTube, Maps, Stocks, Calendar, Messages, Calculator, Clock, Weather, Notes, iTunes, App Store, Settings and Contacts (6).

The iPhone was developed by Apple and AT&T Mobility, but Apple was allowed to control every stage of the hardware development to help avoid problems that had arisen from their efforts with Motorolato produce the ROKR E1 (4). In exchange, AT&T received 5 years of exclusivity, roughly 10 percent of iPhone sales in AT&T stores and a thin slice of Apple's iTunes revenue (5). The phone is becoming more accessible with other wireless providers around the world.

The A-GPS is a “carrier network dependent system which can, under certain conditions, improve the startup performance of a GPS satellite based positioning system. (5)” The system was made available after FCC mandated that all cell phone locations be available to emergency dispatchers. This allows the device to locate itself on a map using the carrier’s information alone (5).
