As expected, Apple on Monday unveiled the iPhone 4, the latest version of its popular smartphone, which will include a video calling feature known as FaceTime, a gyroscope, a video editing app, retina display, iBooks, and more.

The phone – which will be available in white and black – will go on sale June 24 in the U.S., France, Germany, U.K., and Japan. More countries will be added throughout the summer, for a total of 88 by the end of September.
