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 was released on June 24 in six countries, prior to anticipated release worldwide.
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 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. 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 conferencing capability, FaceTime.
