Secret research and development
In 2004, Apple Corp summoned more than 1000 internal staff to develop iPhone team and began to be arrested.
Classified as a highly confidential project, it is called "Project Purple", including the iPhone's behind the scenes designer, Jonathan Ive. At that time, Steve Jobs, chief executive of Apple Corp, deviated from the original iPad tablet computer to mobile phone. The Apple Corp's secret cooperation with AT&T created some hardware and software devices - the Cingular wireless network - AT&T, which gave Apple Corp investment and great freedom, and spent about $$1.5 billion in 30 months. In exchange, Apple Corp guarantees that iPhone will be sold exclusively to AT&T in the United States within 4 years.
Apple started a development plan for iPhone with "Purple 2", when Nintendo's NDS began to go around the world, and iPhone, such as multi touch, was obviously influenced by the design elements.
