In its pursoot to stay atop the technology world, Apple Inc. has unveiled its newest release. It has unveiled the iPhone 4S and lower prices for its older versions. The iPhone 4S, the sequel to its iPhone 4, has a number of new features including your own assitant Siri and better resolution on its photo and video camera.

With a new feature called Siri, iPhone owners can hit their home button, and ask about the time and weather, or to make a phone call. It also works with reviews website Yelp for help, say, in finding Indian restaurants in San Francisco. Apple purchased Siri nearly a year and a half ago.

The iPhone 4S’s camera has an 8 megapixel sensor, up from 5 megapixels in the iPhone 4, and will perform better in low light and offer more vibrant colors.

“For many customers, the iPhone 4S will be the best camera … and video camera they’ve ever had, and they’ll have it with them everywhere they go,” said Apple senior vice-president Phil Schiller.”
