iPhone 6s is the name for Apple's 2015 lineup, consisting of iPhone 6s and iPhone 6s Plus. The iPhone 6s was introduced on September 9th, 2015 at Apple's event in San Francisco. Apple says iPhone 6s is the "most advanced smartphone ever". Available in silver, gold, rose gold and space grey, the 4.7-inch retina iPhone 6s packs in more advanced features than ever before — including what Apple calls 3D Touch. 3D Touch not only recognizes typical gestures, but also force gestures. It gives shortcuts on the home screen to frequent actions, and also inside apps.
