Development of the iPhone began with Apple CEO Steve Jobs' direction that Apple engineers investigate touchscreens. Apple created the device during a secretive and unprecedented collaboration with AT&T Mobility Cingular Wireless at the time at an estimated development cost of US$150 million over thirty months. Apple rejected the "design by committee" approach that had yielded the Motorola ROKR E1, a largely unsuccessful collaboration with Motorola. Instead, Cingular gave Apple the liberty to develop the iPhone's hardware and software in-house.
iPhone is more than just a phone. It combines three devices in one: a revolutionary mobile phone, a widescreen iPod, and a breakthrough Internet device. All that and more makes it the best phone you’ll ever use. With the Multi-Touch interface on iPhone, you can make a call simply by tapping a name or number in your contacts or favorites list, your call log, or just about anywhere. Visual Voicemail lets you select and listen to messages in whatever order you want just like email. The first thing you’ll notice about iPhone 3GS is how quickly you can launch applications. Web pages render in a fraction of the time, and you can view email attachments faster. Improved performance and updated 3D graphics deliver an incredible gaming experience, too. In fact, everything you do on iPhone 3GS is up to 2x faster and more responsive than iPhone 3G.
The iPhone allows audio conferencing, call holding, call merging, caller ID, and integration with other cellular network features and iPhone functions. For example, if a song is playing while a call is received, it gradually fades out, and fades back when the call has ended. The first two models only support voice dialing through third party applications. Voice control, available only on the iPhone 3GS, allows users to say a contact's name or number and the iPhone will dial.
