I cant find how to set ring tones PER caller like I used to be able to do on my Trio. Under contacts edit there is no place to set a ring tome for the contact.
Plus is there a way to set a ring tone for callers who are not in my address book (unknown callers as it was in my trio)
Under Phonebook, select the contact you want to set a custom ringer to and then select Edit. Once in the edit screen, hit your menu button and select Add Custome Phone Tune. See if this is the same for your BB model.
