Jacob - 

Please make sure you have the "Show Ringtones Tab" option checked on your iPhone's home page in iTunes. Without that it wouldn't show up. There are many comments here that mentions the same.

Silent ringtone is a great idea!

:]

It does have...it's just not enabled by default...there are some great comments here that tells you how to do that.

Follow the comments here and they tell you how to make sure to enable the Ringtones folder in iTunes.

Try lessening the length a tiny bit more and see if it helps. I remember of having the same issue when I tried a slightly lengthier duration than the 8 seconds that I have in the demo. Hope it helps.

Well said Debbie...those great comments made it even more useful. Thank you for bringing that up.

Please try the same again and before that I would recommend you read some of the great comments here and that sure would help your issue. Let us know if not.

Jacqueline - don't know which operating system you are using but if it happens to be Windows then you might want to make sure to show the file extensions. Under Windows Explorer "Folder Options" there is a setting of a sort of "Hide extensions for known file types". You might want to uncheck that option so Windows can show you the file extensions. There are a few great comments here that explains exactly what to do. Hope it helps.

What OS are you using? In Windows you need to turn on the "show hidden files" option, just keep that in mind. Please share a bit more information about the problem and we can try to help.
