Apple's fall product event is typically all about iPhones, but CEO Tim Cook waited until three quarters of the way through the Sept. 9 shindig to bring up the company's popular device. 

But when he did finally unveil the iPhone 6s and 6s Plus, he got big cheers from the crowd. "We have changed everything about these new iPhones," he told the audience.

The next-generation smart phone comes with a new feature called 3D touch, which senses multiple levels of pressure from the finger on the touch pad. This allows for a function called "peek" where a user can quickly preview information without having to open up a different app. 

The iPhone 6s comes in the standard three colors -- silver, gold and space gray -- and in a brand new rose gold color.
