Query: STOP - READ BEFORE BUYING

DJ Ringtones do not work on i-phones. This is not made clear or obvious before purchase. On the contrary, the ad leads you to believe it will work on any common phone. As I have no other cell phone, this was a total waste of money!!!Other than that it was very easy to use and create ringtones. Too bad I have no use for the software.
