As you may already know, iTunes not only sells songs but also ringtones you can use in your iPhone if you pay the correspondent tax, which is $1 apart from the $1 for each song. However, some of us still think that’s too much for a simple ringtone. So if you prefer to save those two bucks for something else, keep on reading and learn how to create free customized ringtones for the iPhone.
First you’ll need to download ToneShop: this program enables you to select the best fragment from your favorite song and convert it to several mobile phone audio formats – including iPhone. Use ToneShop to create the ringtone, select the iPhone profile and save the resulting M4R file in any folder on your hard drive.
Now double click the M4R file and it’ll launch iTunes, creating the Ringtones area in your library right away if this is the first time you work with M4R files in iTunes. If not, the new ringtone will simply be added to your collection.
To transfer the ringtone to the iPhone, simply go to the Ringtones tab inside the iPhone area in iTunes and sync your iPhone. Your brand new personalized ringtones will be available in Settings > Sounds > Ringtone, under the Custom section.
