Erasing stock MP3s for memory space
 

I am not a fan of the MP3 ringtones (music, etc). I just like normal phone ringers. Because of that and wanting to free up memory space, before I delete the stocked MP3s, is there anyway that I can backup only the MP3s/sounds before I delete them?

I don't think so. I looked as well and couldn't find a way to do it. I tried to download a different mp3 ringtone and give it a name that is the same as a stock mp3 ringtone, hoping that it would write over the other file and then still let me delete it. Didn't work either.
