Is there a way to set a ringtone for calls that show up as Unknown? My work apparently blocks caller id so when they call me it shows up as Unknown... I would like to set a separate ringtone for this. Any help would be greatly appriciated. Update: googling suggested that if you make a contact from the unknown call (menu - save to contacts) you can put the ringtone there. I was able to get it to make the contact and specify the ringtone, but it still didn't work. The phone ignored that contact. all of my other contacts specified ringtones work.
