Apple officially unveiled its new iPhone 6s and iPhone 6s Plus today. The new models look identical to their predecessor as expected, but now a fourth color option has been added to the usual mix of Space Gray, Silver and Gold – a pinkish Rose Gold. Made out of a stronger 700 series aluminum and tougher Ion-X glass, the iPhone 6s and 6s Plus feature a faster Touch ID 2 fingerprint sensor, faster wireless antennas, an A9 processor that's up to 70% faster than before with up to 90% faster GPU performance, as well as a 3D Touch Retina display - Apple's iPhone version of Force Touch that can sense light and deep presses for quick access to additional gestures like previewing app and email content without having to open it.
