The iPhone 4S benefits from an 8 megapixel camera with a hybrid IR filter for more accurate colors and a five element f/2.4 aperture lens for 30 percent sharper images
In his first product launch since becoming CEO, Apple's Tim Cook has announced a new version of the iPhone at Apple HQ in Cupertino, California. The iPhone 4S retains the ground-breaking Retina display technology and glass back of its predecessor, but has undergone something of an internal overhaul. Apple's new smartphone gets a brand new dual-core processor, an 8 megapixel camera capable of also shooting full high definition video, and a new personal assistant application that uses voice recognition. The 4S also promises up to double the previous download speeds and will be available on over 100 carriers worldwide.
