Cupertino (USA): Apple Inc unveiled a faster, more powerful iPhone in its first major product event in years without Steve Jobs presiding.

New CEO Tim Cook led the show after Jobs, who has been battling health problems, resigned from the post in August.

Cook, wearing a navy blue button-down shirt and jeans, opened by calling his nearly 14-year tenure at Apple "the privilege of a lifetime." Those in the audience clapped as he entered, but the reaction seemed more muted than what Jobs had recently received.

Cook said the latest iPhone, which came out in June 2010, sold more quickly than previous models, but the iPhone still has just five percent of the worldwide handset market.

Apple is hoping to grow that with a new model. The new iPhone 4S has an improved camera with a higher-resolution sensor. The processor is faster, which helps run smoother, more realistic action games. It's also a "world phone," which means that Verizon iPhones will be useable overseas, just as AT&T iPhones already are.

The new iPhone also comes with new mobile software, iOS 5,that includes such features as the ability to sync content wirelessly, without having to plug the device to a Mac or Windows machine.

IOS 5 will also be available on October 12 for existing devices, the iPhone 4 and 3GS, both iPad models and later versions of the iPod Touch.

Apple said October 12 will also mark the launch of its new iCloud service, which will store content such as music, documents, apps and photos on Apple's servers and let people access them wirelessly on numerous devices.
