Full Song Ringtones

How to make full songs IPhone Ringtones?

I know how to make the 30 second clips but I want to know if there is a way to make an entire song a ringtone or how to extent the limit from 30 seconds (which im sure is file size limitation) to something like a full minute. Im just tired of looping songs…call it picky…
