Apple today announced that iPhone 4S will be available in China and 21 additional countries on Friday, January 13. iPhone 4S features Apple’s dual-core A5 chip for fast performance and stunning graphics; an all-new 8-megapixel camera with advanced optics; full 1080p HD-resolution video recording; and Siri, an intelligent assistant that helps you get things done just by asking. “Customer response to our products in China has been off the charts,” said Tim Cook, Apple’s CEO. “With the launch in China next week, iPhone 4S will be available in over 90 countries, making this our fastest iPhone rollout ever.”

Just in time for the holidays, Apple’s fifth Manhattan store opens for business at New York’s world-famous Grand Central Terminal at 10 a.m. on Friday, December 9. The store overlooks the historic Main Concourse and features two Genius Bars, entire rooms dedicated to Personal Setup and Personal Training, and an expert team of 315 employees. Holiday shoppers can test-drive Apple products, attend 15-minute Express workshops, get free technical support, and more.

In an interview at National Geographic’s Adventure blog, director Tim Kemple of Camp 4 Collective — an outdoor video and film production company — describes using iPhone 4S to shoot a hi-def music video at the Great Salt Lake as an experiment in remote location capture. Kemple reports getting excellent video from iPhone 4S, noting that “because it’s always with you means you end up using it when you’d least expect.” The interview includes tips for stabilizing shots, optimizing for iOS 5 features, using helpful apps in extreme environments, and shooting in low light.
