Find My Friends shows my old phone I traded in my 4S recently to upgrade to a 5S, and restored the 5S from the last 4S backup, so they both share the same phone name ("Adam's iPhone"). However, when I use the "Find My Friends" app, it displays "Share my location from:" and shows "Adam's iPhone" twice.

I visited this Apple Support page, which suggested to log into iCloud and disable the second phone from there, but only one phone is listed on that page (along with my iPad and iMac). Is there another link that explains how to remove the old phone from "Find My Friends"?
I found the way to do it on iOS 8:
Settings > Privacy > Location Services > Share My Location > From

Then is will show the list of current and old phones.  It has instructions:  "If you're no longer using a device, swipe left on the device name, then tap Delete."

It worked for me!
