Not sure what you mean...are you looking to purchase a certain ringtone in the iTunes store or did you want to make your own ringtones for your iPhone? There are a few threads that have links to the steps to successfully create ringtones for your iPhone. Just use the search box so you can find those threads and see if the links help you out. You can also use one of many free ringtone making apps available in the app store. You will have to sync any ringtones you make on your iPhone back to iTunes before being able to use them as ringtones as they have to be in the correct format so that the iPhone can view the songs as ringtones instead of just seeing them as another music file.
