If you’re like most iPhone 4s owners, you probably have a ton of great ringtones saved on your device but can’t seem to find the one you want to use. Here’s how to set a new ringtone on your iPhone 4s:

  1. Open the Settings app on your iPhone 4s and tap Sounds.
  2. Tap Ringtone and then select the ringtone you want to use from the list of available options.
  3. If you want to make sure that the ringtone will play when your phone is locked or when it’s silent, tap Silent Ringtone and then enter a passcode if necessary.
  4. Tap Save at the bottom of the screen and your new ringtone will be ready to use! ..
