So, i've submitted an update to my app. This one will allow you the opportunity to download the tone as a ringtone!!! After i've received so many peoples emails requesting this, i've decided to implement it. The update is awaiting review, but it's going to be awesome!! I currently have my ringtone set to a 10000 Hz tone. It works great! After you download the ringtone, it's saved in the phone. Then, simply connect your phone to iTunes and transfer it through "file sharing". (click on the iPhone or iPod and click the "apps tab") Above is an Image to show the location of the file sharing.
