iPhone 4 was released on June 24 2010 in six countries. The iPhone 4 has all the features associated with an iPhone; only major changes from the iPhone 3GS are listed below. The most noticeable difference is a new design. The primary new design feature 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. It has an Apple A4 processor and 512 MB of eDRAM, twice that of its predecessor and four times that of the original iPhone. Its 3.5 inches (89 mm) LED backlit liquid crystal display with an increased 960-by-640 pixel resolution is marketed as the “Retina Display.” It comes preinstalled with the iOS 4 operating system, and is currently the only device to support a new video calling feature, FaceTime.
