I am not familiar with Zuniga but I do know of an app that allows you to set ring tones, wallpaper, notification ring tones and contact ringtones. Trust me, there's thousands upon thousands of choices and maybe you'll find some that you'll like. Go to your Playstore and search for the ZEDGE app. Download it and start choosing.

I can't answer this better than the official Apple page on the subject:
Where are my iTunes files located

there are all kinds of sites that offer free ring tones
www.allfreeringtones.ca
www.free-ringtones.cc
gallery.mobile9.com/c/apple-iphone+3g-ringtones_2018/1/
www.zedge.net/ringtones/2111/apple-iphone-3g-ringtones/

To change ringtones and message tones I use one of two apps.
Zedge has a large selection of sounds for you to select and download for free and it will give you the option to add it as a ringtone or notification tone.
Or you can use Ringdroid this allows you to add any mp3 file you want and again you can do it as a ringtone or notification.
So those are two fantastic apps that I use a lot. Zedge also has a large selection of wallpapers for you as well.
Now if this still doesn't work then if you go Settings/Sound/Notification Ringtone this will bring up a menu system that will allow you to select a sound either one installed on the phone from boot or one you have added yourself.
This should help you, also selecting Phone Ringtone instead of Notification Ringtone then the same kind of menu system will come up.

Hope this helps.

we can't install themes on samsung star wifi.. but, you can download wallpapers.. you can go to zedge.net to download wallpapers..
