When he calls, does his name show up on the screen for the Caller ID? Have you tried completely deleting his contact and then adding it back as new? If you want before doing that, after you have changed his ringtone, do a reset on the phone. Hold the sleep/wake and home buttons together until you see the Apple logo and then release. After the phone restarts, see if the ringtone works for his calls.
