So my brother emailed my mom some Apple m4r ringtone files. I imported them into iTunes (latest version as of today), and they show up under the 'tones' section of the computer's library. I click 'sync', and iTunes goes through the 5 step process of syncing the iPhone (running iOS 6). But the ringtones never show up on the iphone. After syncing is done, i click the 'iphone' button, and then i click 'on this phone', and then 'tones', and there's nothing! it says zero items! Yet the tones are still on the local library, they just refuse to sync.
I really dont understand how to use iTunes, so I am probably doing something very obviously wrong. Any help would be appreciated!
