Resolved Question: lost ringtone on iPhone?

I downloaded 2 ringtones from iTunes. I had them set as ringtones for individual contacts. I also downloaded one that was for all other calls. Both were songs. When my phone rings now, it is a factory ring. I looked in all the places I could think of on my phones and my computer and can’t find them. I synced. No luck. I went to iTunes to purchase and, of course, it gives me a warning that I’ve already purchased that ring tone. I could spend the $1.29 for the ringtone again, but where did they go? Will I lose them again?
