The iPhone 4 is the fourth generation of iPhone, and successor to the iPhone 3GS. Introduced on June 7, 2010 at the WWDC 2010 at the Moscone Center, San Francisco, It's the first device to support FaceTime, Apple's video calling application. It has an Apple A4 processor, 512 MB of eDRAM, a 3.5 inches (89 mm) LED backlit liquid crystal display with 960-by-640 pixel resolution, and the iOS 4 operating system. The iPhone 4 has all the features associated with an iPhone. The most noticeable difference is a new industrial design. The primary structure is a stainless steel frame, which additionally acts as both antennae. The internal components of the device are situated between two panels of chemically strengthened aluminosilicate glass. Additional changes include the Apple A4 processor, a high resolution display, marketed as Retina Display, and an embeded video conferencing application, FaceTime.
