Apple ipod

Free ringtones for the iPhone through iTunes 9?

trying to get ringtones on my iPhone, just bought an iMac and when I synchronized phone with my computer deleted all my ringtones. I know how to get to m4r but for some reason the ringtone file is not displayed. I tried to create a ringtone folder did not work either. other ideas and is driving me crazy.

iTunes makes me mad, I use this site free http://www.ventones.com/free-ringtones-for-iphones
