You cant make ringtones from your mem. card. they need to be transfered to your phone, not the card. assuming you have the correct ringtone guidelines(i.e-8,000khz/8bit/mono) once you have that done, you need to disable your usb reader on your phone. Use webjal or mediajal to transfer the tones. If you need more hlp. IM me at cnjsimmsatsbcglobaldotnet, I have about 400 ringtones so far and am making more as we speak.
