I've got a 3GS running 3.1.2 unlocked/JB, I've SSHed into the phone and moved my created .caf file (after converting it to .aif), renamed exactly the same as the file it is replacing, and I get no sound. I have even downloaded 2 different ones from this website that were formatted by other people who got them to work and they are still silent on my phone. Any suggestions on what do to get the sound to work for the messaging tones? I've searched for help the last hour and a half but haven't found anything specific in terms of troubleshooting, and I've tried all methods listed for the initial loading of tones onto the phone. I'd prefer not to have to purchase tonesfx if I don't have to. Thanks!
