I went to edit my device in my profile, there was not option to select a 5s. I don't think 5c was there either. Just a heads up.
I was able to edit mine under the settings drop down menu from the main site.

The problem is that the 5S and 5C are at the very top of the list, not logically underneath the 5 in the Apple section of the list.
