What’s So Special About the iPhone 4

Apple set out to revolutionize the cell phone experience once again with this week’s launch of the iPhone 4. This new mobile device boasts advanced features like video calling, a 5 megapixel camera with LED flash, HD video recording, multitasking functionality and 40 percent longer talk time.

The iPhone 4 features an all-new design of glass and stainless steel and is said to be the thinnest smartphone in the world.

“iPhone 4 is the biggest leap since the original iPhone,” said Steve Jobs, Apple’s CEO. “FaceTime video calling sets a new standard for mobile communication, and our new Retina display is the highest resolution display ever in a phone.”

According to Apple, the iPhone 4 will be available in the US, UK, France, Germany and Japan on June 24, with prices starting at $199. The new device is expected to roll out worldwide to 88 countries by the end of September.
