Although many were expecting Apple to announce the iPhone 5 at its "Let's Talk iPhone" press event today (Oct. 4), the company did unveil the latest device in its lineup, the iPhone 4S. Although it looks the same as the previous version, it has a lot of high-tech bells and whistles, including new voice-activated intelligent software called Siri, a dual-core A5 processor chip and a 8-megapixel rear camera.
