I have a Samsung e747 and for the love of god(fathers) I cannot add ringtones. I have NO INTERNET on my phone. I can add ringtones to set as the alarm but when I try to add them as the actual rigntones it says "NO DRM. Cannot be set as ringtone" or something to that effect. I even bought ringtones but I can't add them. I tried making my own ringtones. What can I do?
