I downloaded a 30" mute ringtone in .m4r format, my guess is I have to drop it onto iTunes to install it on the iPhone.
The contact I want to mute is not in my phonebook, I recall that a while ago I attached a certain tone to a contact, once I deleted the entry off the phonebook and way later on I got a text from the same person the ringtone remained, do you think I could add the number to phonebook, personalise the ringtone then delete the contact and keep the tone?
Grazie
