Apple announced the iPhone 4S and not the iPhone 5 at its Let's talk iPhone at the Cupertino, Calif., headquarters Tuesday. In the one-hour long media event, Apple Inc. unveiled its new world phone, iPhone 4S, and a new iPod.

The new device will be available in the U.S., Canada, Australia, the UK, France, Germany and Japan from Oct. 14, followed by 22 additional countries from Oct. 28, at the price of $199 for the 16GB model, $299 for the 32GB model and $399 for the 64GB model. The device will be available from Apple's Web site and retail stores; carriers are AT&T, Sprint, Verizon Wireless.

The coolest feature of the newly launched iPhone 4S is its Siri voice recognition and detection. Siri is a whole new way of interacting with your iPhone, using just your voice, said Philip Schiller, Apple's Senior Vice-President.
