iPhone4S First Review: Here is the first review of the new iPhone 4S. This video is highly detailed with visual annotations. The new iPhone 4S features "Siri", an Artificial Intelligent (A.I.) personal assistant along with a vastly improved camera, HD 1080P video camera, and a super-fast new chip. The iPhone 4S is available from Verizon, AT&T, Sprint and soon Virgin Mobile will also have the iPhone 4S. Unfortunately, T-Mobile won’t be getting the iPhone 4S.
