anything that you've added that isn't part of the OS is stored on your SD card (such as ringtones). they'll be in a folder somewhere on that card. attach it to a PC to find them.I tried that. I have a file manager, and it can't find them either. They show up in the ringtones when I go into Settings > Sound & Display, but they don't show up in any searches. Very strange. I found the file that contains the stock ringtones, but they are not there.
