iTunes Ringtones store have started going live in stages. First, a note appeared when I enabled the Ringtones column, informing me that the iTunes store allows me to create ringtones from many songs. Next, grayed-out ringtones started appearing next to some tracks. I purchased a track--two actually because the first one would not download no matter how many times I checked for purchases--and after it downloaded to my purchases tapped the ringtone bell to create my own ringtone. As the gallery shows, I was able to use the m4r/m4a rename trick to get my custom ringtones to sync with the iPhone. Ironically, $3 later, my purchased iTunes ringtone will not.
