Installing Ringtones on my iPhone with Windows XP and iTunes

I wanted to install homemade ringtones onto my iPhone like the ones I had previously created for my Sony Ericsson.  For example, when my wife or father calls, I have ringtones which either say, "Debbie is calling" or "Dad is calling."  This way I can tell who is calling without looking at the phone.  

First I created the ringtones using Microsoft's Sound Recorder application which comes with Windows.

With Sound Recorder I created the files I wanted such as "Debbie is calling.wav"

The next step was to drag the wav files to iTunes (version 7.5.0.20), which added the files to the iTunes library.

iTunes put the files in the "Unknown Artist\Unknown Album" folder.

The next step was to right click on the wav files in iTunes and select "Convert Selection to AAC."

iTunes then created and added a ".m4a" format of the files in the folder.

In the next step, I created the folder "Ringtones" in my iTunes directory and copied the ".m4a" files there and then changed the extension to ".m4r"

The next step was to drag the files from the "Ringtones" folder to the "Ringtones" Library in iTunes.  

The next step is to sync your iPhone with iTunes.

The ringtones are now on the iPhone.

Mission complete!
