how do I place a ringtone on my new 5c i phone
You need to go into Settings>Sounds>Ringtones to find the default ringtones that come with your device. Just choice by putting a check next to the one you want to use
You also have the choice of going into the iTunes Store and purchasing a long list of ringtones by category
Lastly you can create ringtones from songs or use your own voice to make the perfect ringtone
