Remove custom ringtones from itunes
I am using the latest itunes 11.01.12 version with my iphone 5. I have a number of custom ringtones which appear in the "Tones" section of itunes. I want to remove them completely (not just un-check and sync) and leave the page blank. I have tried all I could with no success.
Please provide guidance!
iPhone 5, iOS 6.0.2, 64GB
