I see that the format for the ring tones on my Samsung SGH-T509 are in 'mid' and someone had forwarded me a text which included a sound. I was able to save it and it can be used as a a ring tone. Where else can I find free 'mid' format ring tones, like I can make my own. I tried creating my own but it was in 'mp3' format and I couldn't use it as a ring tone.
