i'm familiar with the whole GarageBand "Send to iPhone ringtone" method but it's not my preferred way of working.

however i'm trying to figure out how to get a ringtone to loop. can iToner do it when it transfers the file? or do i need to set a loop point in the sound file itself in an editor somehow?

The file will loop automatically when when used as a ringtone. I just tested it and it's pretty darn close to being seamless.

huh, okay i'll have to look at my sound files more closely. in my experience there's a marked pause between rings.

The ringtone I tested was voice so there certainly a space between them, but it's looping almost instantly. Another option is to create the loop as you want it and use iToner to send that file over (ie. one audio clip you have looped 10 times).
