Discovered a problem today which is reasonably obvious when I think about it. I have various customised ringtones. They (necessarily) live on the sd card. when the phone is plugged into a computer it essentially takes the card OUT of the phone loop to allow access. When the phone rings it can't "find" the customised tone (as the sd card "isn't there) and so defaults to something on the phone itself. which was inaudible. Any thoughts?
