Bit of help needed (for all you brainiacs out there) Sister's got an iphone4. All of a sudden and without warning all incoming calls are coming through as blocked, She can ring out OK but not receive calls. Nothing has been jailbroken or anything.
EDIT: Tried phoning her from my mobile and as I am a contact it came up OK
