I have enabled call forwarding from my other phone to the iPhone. When I receive a forwarded incoming call, there is a "Call forwarded" message showing up for only 0.5 sec and then it disappears and there is a standard incoming call screen. So in most cases I don't know, whether the call was forwarded or not.
Is there any way to add such indication to incoming call screen, e.g. make the message not disappear after 0.5 sec?
