Development of the iPhone began in 2005 with Apple CEO Steve Jobs' direction that Apple engineers investigate touchscreens He also steered the original focus away from a tablet, like the iPad, and towards a phone. Apple created the device during a secretive 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 and even paid Apple a fraction of its monthly service revenue (until the iPhone 3G), in exchange for four years of exclusive U.S. sales, until 2011.Jobs unveiled the iPhone to the public on January 9, 2007 at the Mac world 2007 convention at the Mo scone Center in San Francisco. The iPhone went on sale in the United States on June 29, 2007, at 6:00 pm local time, while hundreds of customers lined up outside the stores nationwide. The original iPhone was made available in the UK, France, and Germany in November 2007, and Ireland and Austria in the spring of 2008.
