SAN FRANCISCO, Sept. 9 (UPI) -- Apple unveiled the newest iPhone on Wednesday -- calling it the "most advanced smartphone in the world" during a convention in San Francisco.
The iPhone 6S adds a host of improved capabilities -- including a 12-megapixel camera, more durable screen glass and new available colors.
The iPhone 6S and iPhone 6S Plus will sell for $199 and $299, respectively, the company said.
"These are the most popular phones in the world. But more important to us, it's the most loved phone in the world," Apple CEO Tim Cook said.
"While they may look familiar, we have changed everything about these new iPhones."
The new iPhones, which feature Apple's latest operating system, will go on sale this month.
Cook also announced the iPad Pro on Wednesday during the company's September keynote at the Bill Graham Civic Auditorium. Cook said the device has "the biggest screen on an iOS device" at 12.9 inches and "more power and performance than any iOS device."
By comparison, the most recent iPad Air is 9.7 inches on the diagonal.
The iPad Pro features 5.6 million pixels, more than a MacBook Pro with a retina display.
It also features an A9X 64-bit processor, with two times the memory bandwidth of its predecessor, the A8X. It features a battery life of 10 hours and will be compatible with the company's new physical keyboard to be sold separately.
Additionally, Apple's Watch Sport is now available in gold and rose gold finishes. Small versions of the watch in these finishes will be available for $349, and larger versions for $399. Sales begin Wednesday.
Apple is also debuting its Pencil, a "highly responsive" stylus with advanced technology that can measure "pressure, tilt and stroke."
