the samsung sph-a660 doesn't support mp3 files. it does support midi files tho.
If you want to try anyway, try using a mobile phone uploader on the web. upload the file using their tool and put in your phone number. It'll send you an sms with a URL, just go to that url using the phone browser and it should download. you'll probably get a file type not supported or some sort of error message. If the mp3 file does work, plz let me know.
Can anyone help me -- is it possible to load mp3 ringtones onto a Samsung A660 phone from a PC? If so, please describe how it is done. Thanks. DLB
