HTC Aria : Way To Get Ringtones For Contacts?

I just got the phone 2 days ago and I am having problems getting custom ringtones for contacts. I can set the default ringtone to something different and that works, but when I try to change it for one specific contact it still play the default one. I have tried changing it in the contact it self, i changed it from the app i downloaded, and i even set it using the music player. I don't know if it is something wrong with the phone or if its is something with 2.1. I went back to best buy where i got it and the one of the workers said the same thing happened to his hero and incredible when he updated to 2.1.
