How do we use MP3's as ringtones on the INSTINCT???

I know this phone just came out but does anyone know how to use MP3's as ringtones on it yet? Even just voice recordings as ringtones?
Thanks!

for custom ringers go to Myxer - Download Ringtones and More

i'm also searching for this info.i dont need custom ringtones.having ones own mp3,how do you load the ringtone.i tried putting it on the sd card but thats a no go.anything mp3 i try to transfer to the phone always go to the music folder,i still cant figure out what i'm doing wrong or the proper procedure to load ringtones to the instinct,thanks.

Go to the site in post #2 and load your custom ringtone to your phone.

i still cant get it done.tried the site but the email message is not being received by my phone for whatever reason.
