Confession: I have yet to find any impetus to change from the default iPhone ringtone, no special need to switch to "I like big butts" or any other sitcom-worthy wrong-tone, wrong-time humiliator. I rock Marimba.
But for those of you who want something different, something with that "premium" sound to match your -- tastefully -- gold plated MacBook Air and exotic monkey-picked tea, iRingPro has got your back, with more civilized intervals and stately sound.
If ringtones are your thang, check them out.
