I'm trying to edit the SentMessage.caf and sms-received1-6.caf files on the Star Wars Sounds package from Cydia. I got sms-received6.caf to work properly, but I can't seem to get the others to work at all. What am I doing wrong? I've tried different file formats like wav, mp3, and m4a. The one I got to work is wav format. Is there another way to do this? I'm pretty much stuck. Any help would be greatly appreciated.
