On Sept. 9, 2015, Apple unveiled the iPhone 6S and 6S Plus as the "most advanced smartphones in the world," Apple CEO Tim Cook said. The phones were available in four aluminum colors; rose gold, gold, silver and gray.
Apple unveiled the iPhone 6 and iPhone 6 Plus on Sept. 9, 2014. The phones have curved edges and bigger screens that measure 4.7 inches and 5.5 inches, up from just 4 inches on the iPhone 5S. The larger iPhones have what Apple is calling "Retina HD" displays.
The 5S comes in metallic hues and features performance upgrades, including the first 64-bit chip in a smartphone. Apple's A7 has tested at up to twice as fast as the iPhone 5's processor. There's also a fingerprint scanner for security and a motion co-processor that will let the phone be used as a fitness tracker along the lines of a FitBit.
