I need help with trying to figure out how to disable the radio in the music application on the iPhone 4. My son is 11 and I do not want him to have access to unlimited unsensored songs....I want only what I approve to download for him. This radio appreared with the most recent software update. I even went to the Apple Store today and they said to hook the phone up to the computer and through Parental Controls, the radio may be disabled. I saw all that, but the administrative password that it's supposed to require me to enter, is not popping up, therefore my changes made are not saved. Please help.
