Apple Inc. launched the original one. This Iphone 5S looks like a real Iphone but it uses iOS looking Android 4.1 Jelly Bean. You will see Google Play Store opening when you press the App. Store bottom.
It has 1 Ghz Mediatek processor and 512 MB RAM. It also has 4" Apple's Retina display. These features are less than it should have been.
However, the Apple Inc. might launch real Iphone 5S around the end of 2013.
