The iPhone is a touchscreen-controlled, multimedia-equipped smart phone designed and manufactured by Apple. The iPhone allows Internet access through Wi-Fi and cellular data network services, allowing web browsing and email to be accessed directly from the device. The 3.0 firmware update delivered a new function known as the “Spotlight Search,” which allows fast and simple searching through all the iPhone’s content, including email folders. Searches can also be performed solely within the email client’s individual folders. Writer Bio
