This is one of the most common design flaws in the IPhone. After weeks of pouring through thousands of threads and posts a dozen layers deep in google searches, the solution still has not been found. Ringtones cannot be sync'd from Itunes to the Iphone 3g. Ringtones can be bought, downloaded, and/or created and played in ITunes just fine. We figured out how to create the ringtone folder (the drag-and-drop method), and we figured out how to convert ringtones to M4r format (the desktop-rename-drag-to-ITunes method). They show up in the ringtones folder, and the sync boxes are all faithfully checked. Sync until the cooling fan blows, and you will still have the same old crappy ringtones that came with the IPhone. The simple joy of adding ringtones to the IPhone is not to be enjoyed by millions of owners. Any owner of Blackberry, Nokia, Motorola, and Droid can do it seconds without any hacking skills at all. IPhone can't do it. Go figure. The person who figures out how to hack the IPhone where it will sync ringtones with a PC will be wealthy beyond measure. So, please please share this darkest most evasive secret with me. Just between you and me; how can Itunes ringtones sync from a PC to the IPhone?
