I get my ringtones from ventones.com. They send me the 30 second audio in a text, and I can save it as a file. I have two options: save it on my phone, or save it to my microSD card. If I save it to my phone, I can access it on the "ring style" menu, and set it as my ringtone. If I save it to my SD card, it doesn't appear in the "ring style" menu. It's taking up too much memory on my phone to save ringtones, and I'd like to just store them on my card and still be able to set them as my ringtone. How can I do this?
