You’ll be confused about all the different ways and means, and cannot tell which the most practical solution is. Further more, most results mention the same way – make ringtones for iPhone using iTunes. As far as I know, many address that this approach doesn’t work on their iPhones, or it seems quite difficult to follow. So, for the further simpleness and convenience, you’d better adopt a second method – draw support from an iPhone ringtone maker.
