Samsung SCH-A670

ok i realize that i've brought this stopic up in the past before but it just happened to me again. You know when you have specialized ringtones for different people in your contacts list do those ringtones every like change for some reason when that particular person calls you on your samsung a 670? I was also just thinking that maybe the change of ringtones has to do with that when you add/delete rintones from your "my tones" folder or something of that nature? I don't know does anyone else ever experience this or haev any feed back for me. Im not complaing so don't get me wrong im just bringing it up. after about 2 1/2 months of using the phone i can honestly say that i love it completely. it works beautifully well.
