The Evolution of The iPhone
The iPhone is a series of best selling smart phones licensed with AT&T. Created by Apple, the iPhone continues the line of innovative Apple products such as the iPod mp3 player. The iPhone has become famous for its application system, a marketplace of downloadable applications that give the iPhone unlimited functionality. Since 2007, there have been four models of the iPhone with a new phone released each year.
The Original iPhone
The original iPhone was created as a hybrid between cellular phone and PDA technology, utilizing new designs such as a touchscreen interface. The glass touchscreen was unique for its multi-touch functionality. The user could touch multiple points on the screen for additional functions (such as zooming). The keyboard and mouse controls were incorporated entirely into the touch interface, similar to a tablet PC. Internet access was provided through the EDGE network. The original iPhone was released with a 4GB and 8GB model, with a 16GB model released later.
The iPhone 3G
The iPhone 3G was the second generation of iPhone, released in July 2008. The iPhone 3G came with much of the same hardware as the original iPhone, but had an increase in software functionality. The major introduction for the iPhone 3G was the Apple App Store. The App Store allowed users to purchase and download applications, small programs which added additional functions to the phone. This became a trademark of the iPhone brand that has continued to this day. The iPhone 3G was also the first iPhone built to use the 3G wireless network for internet access – the original used only the slower EDGE network.
The iPhone 3GS
The iPhone 3GS, released in June 2009, was created with a focus on hardware improvements. The display screen for the phone was updated to use a greater number of pixels and have a richer color display. The processor and memory were upgraded for the first time since the original iPhone, allowing for faster speeds and better performance of applications. A new camera was also added, allowing 3 megapixel photos and video capture in high definition. The iPhone 3GS also included a compass application, using a built in magnetometer.
The iPhone 4
The iPhone 4 is the latest model of iPhone, released in June 2010. The aesthetics of the phone were the focus with an all-new steel frame and glass display. The phone is thinner than previous models – the exterior antenna in the steel housing gives the phone a smaller profile than older iPhones. The iPhone 4 also received a hardware upgrade with a new processor and double the memory of the iPhone 3GS. It also uses a forward mounted video camera (in addition to the rear HD camera) to allow for video conferencing.
