I have one person in my contacts who I have set to a specific ring tone, although it used to work it has suddenly stopped working and now rings with a BB notifier ring tone, still different than the rest of my contacts but not the song I chose.
I have my Storm on a custom profile I made so that my email doesn't make a noise when I recieve one.
Even under the contacts name it says to play the song when they call.. but it doesn't!!
I've been having the same issue and I haven't figured out how to fix it. It's almost as though the phone isn't recognizing that the caller is set up as a contact at all since I noticed that the contact's name doesn't even show, just the number. Very annoying.
