I have diffent ringtones set for each of my contacts. the last couple of days only my default plays. Here is what I got:
Droid 1, rooted, stock rom, overclocked to 800mhz, all of the ringtones I have downloaded form apps ( ringlert, Zedge, ect) Have moved all of the ring tones to my media folder on the SD so they show up as a system tone. go to options assign to contact, boom this has worked great, havn't done anything diffent. now everytime the phone rings I get my default ringer. the custom tones in Handcent are still working.
