The iPhone 4S runs on the new iOS 5 platform and is powered by the company’s new dual-core A5 chip that is said to be twice as fast as its predecessor. Mobile gamers will be pleased that the included dual-core graphics are up to seven times faster than before. The new smartphone’s battery life offers either eight hours of 3G talk time, six hours of browsing, nine hours on Wi-Fi, ten hours of video playback, or 40 hours of music. The 4S features a new 8 megapixel camera sensor. Users are no longer asked to choose between GSM or CDMA networks, as the 4S supports both.
