Here are the instructions to create a custom iPhone Ringtone from any MP3 using Quicktime Pro.  I’m a Mac user so the instructions are using a Macbook Pro.  This tutorial assumes that you have your Mac set to show file extensions. Don’t know if it’s the same using Quicktime Pro for Windows.

1.  Choose your MP3.  From what I’ve read on the Web the file needs to be :30 or less. Let’s call the file example.mp3

2. Open example.mp3 file in Quicktime Pro.

3. From the File menu choose Export.

4. When the Export menu appears you have a drop down menu with choices. Choose Export: Movie to iPhone.  I know, I know it’s a sound file, not a movie but choose Export: Movie to iPhone anyway.

5. Click Save.

6. Now you have a new file called example.m4v.  M4v is the file format for iPhone video, but you need the iPhone ringtone format.

7. Do a “Command Click” also known as a “Right Mouse Click” on your example.m4v file. Choose the Get Info choice.

8. When the Info box pops up you will see the Name & Extension box.  In that box you will see example.m4v.

9. Change the file extension from .m4v to .m4r.  Close the info box.   Mac will ask you if you are sure you want to change .m4v to .m4r.  You chose Use .m4r. So now your file is named example.m4r.

10.  Open up iTunes and drag-and-drop the example.m4r file into the ringtones directory in iTunes.  Sync up your iphone.  Be sure to check the iPhone’s iTunes Ringtones tab to sync ringtones.  After the sync is complete on your iPhone go to Settings > Sounds > Ringtone.  You will see example under Custom.
