How to save audio files from an email on an iPhone 4?

I have sound files I received via email and I want to save them on my phone so I can use them as ringtones. Is it at all possible to do this without downloading an app or jailbreaking my phone?

Easy(Use Your PC). You have to download the music from your email. You just have to click on it an it will download. Then connect your iphone to you PC and copy the file.

Or You can sign in you email on the iphone and click on the music attachment file to download and save it
