I've been banging my head for days now trying to assign a specific ringtone to SMS contacts with no luck. I've tried both Handcent and Chomp and Textra... same problem. All I really want is a different ring assigned on-call system we have. This worked perfectly on my S3 and the DroidX before that. It's too the point that I'm tempted to root stupid phone and install other ROMs to see if they would work.
