Buying ringtones for an iPhone is a simple process that can be done through the iTunes Store. Ringtones are short audio clips that can be used to replace the default ringtone on an iPhone. They can be purchased individually or as part of a ringtone pack.
There are many different types of ringtones available for purchase, including popular songs, movie themes, and sound effects. Ringtones can also be created from personal music files using a computer. Once a ringtone has been purchased or created, it can be added to an iPhone by syncing the device with iTunes.
