I purchased my ringtones from the iTunes Store. Search for the one you want. There will be a selection of individual songs by diffferent artists, albums, and ringtones for that particular song. The ringtones are usually only 99 cents. After you purchase it, it will show up in Settings under Sounds. Then you select the one(s) you want for phone ring, alert tone, etc. In order to assign a particular ringtone to a particular person, you will have to go to that person in your Contacts, then select the ringtone you want for that person.
I always purchase an iTunes gift card for myself so that the iTunes Store doesn’t have my personal credit card info.
BIG THANKS. Exactly the kind of instructions I needed. Printing them off.
Thanks for the tip about the gift card.
As for ringtones, you can create your own for free. Or at least you could in the past. (You need a computer to do that. If you’re a phone only person, maybe a friend can help?) A little googling should help you find the directions for how to do it. Basically, you use a song you already have in your library, then convert it to another format, making sure that you clip it to no longer than allowed (40 seconds? 20? 30? I’ve forgotten.)
Most of my ringtones are from songs in my library.
