For some reason mine doesn't work. Is this for a jailbreaked iphone or not? I synced them but they aren't showing up?
Hmm you'll have to be more specific about what doesn't work about it?
If the ring tones don't show up on your iPhone then they didn't sync correctly. Make sure you follow the steps exactly as I outlined them (refer to the pictures if necessary).
I think some people only import the ringtones, and assume they'll automatically sync to the iPhone. This isn't the case: you actually have to click on your iPhone in iTunes, and then tell the iPhone to sync to the ringtones that are in iTunes.
And no, its not for jailbroken phones (although it would work for jailbroken phones as well). Just try the steps again and it should work for you. If not, let me know and we'll see if we can't solve the problem.
