Hello, So I just got the new iPhone 4 about a month ago. I manually drag songs onto it, but last night i got a ringtone maker app and i followed the instructions to put the custom ringtone. A notice popped up that the settings changed and i agreed so when it synced i left it alone. Today i looked and all my music was gone on my phone. I tried to manually put the music back but it wont allow me to, is there any way to put it back manually?
