What is the difference between iPhone 5 and iPhone 5s?

The iPhone 5s doesn't exist.

There is no iphone 5s… Yet.

Iphone 5s has not yet be anounce may be soon

The iPhone 5s hasnt been released yet, and wont come out until the second half of next year.

IPhone 5S is coming out this year, maybe this month. I am also wondering this question.
