Difference between IPhone 5 and 5s?

I really want this phone case but i have the first iphone 5, and i wanted to know wether my phone will fit into a 5s case?

Typically, yes it will fit. Just make sure it says for 5 and 5s on the package.

They'll fit fine.

It should. The only physical difference between the 5 & 5s is the dual LED.
