When I first got my phone, it made the "Droid" announcement with most of my notifications. Then I added my own music and ringtones...along with a couple of alarm tones. Now...I can not find any of the original tones that came with the phone. I have deleted all of my previously added content, including the folders...yet when I go to set a ringtone, it says there is nothing on the SD card. How do I get it to point to the phone and not the card? Are those tones lost?
