You can either spend money on iPhone ringtones on the iTunes Store, purchase an application that makes them for you, or you can make your own for free.
I make all of my own ringtones from music that I already own. There are a few steps involved here, but overall, the process is pretty straightforward.
Getting Started The first thing you’ll need to do is find a song that you want to convert into a ringtone.
iPhone ringtones can only be 30 seconds long, so if you find something you like that’s 30 seconds or shorter, skip directly to step 9.
