Iphone launched 5s in 2013 with 64 bit processing, open gl 3.0, a better camera and the best new feature is Touch ID fingerprint identity scanner.
I am using this since more than a year. It comes with 16 gb, 32 gb and 64 gb internal storage, weight only 112 gm also its 4 inch LCD screen. I phone has unique feature like facetime, with that you can do video chat anywhere in the world with your data. Iphone 5s camera result is best so far I found.
Iphone 5s put the future in the palm of your hands.
