How does the IPhone work
The newer your iPhone model, the more advanced its mobile chip and the faster its performance. The iPhone uses its cellular radio to connect to your carrier’s voice and data networks wherever you go, but only the 5s and 5c models can work with ultra-fast LTE networks. Three other wireless radios -- Wi-Fi, Bluetooth and GPS -- can connect you to the Internet and other devices and track your location. A built-in proximity sensor turns off the touch screen when you hold the phone close to your ear, and then on again as you move it away. A rechargeable lithium-ion battery powers the iPhone; on a 5s, it can sustain up to 10 hours of talk time on a single charge.
Who created the IPhone
On January 9, 2007 Steve Jobs put sneaker to stage to give one of the most incredible keynote presentations of his life—a life filled with incredible keynote presentations—and in the history of consumer electronics. He said he would be introducing a wide-screen iPod with touch controls, a revolutionary mobile phone, and a breakthrough internet device. But it wasn't three products. It was one product. We got it, Steve. It was the iPhone.
