Attachment ringtones being removed?

Okay, so I have a Samsung Reality, and I used to be able to put ringtones on it by sending them from my email, but now when I send them it removes the attachment and there's no way to save it. I've tried it from my email, and some websites, but it still removes it. It doesn't do it when I get picture messages from other people though. I've tried connecting it as the Mass Storage and copying them into the folder, but that doesn't work when I try for ringtones, although it does work for Music when I try. This is stubborn! Please help!
