I obviously don't want to give too much away as its just an idea, its something I have felt I've needed on more than one occasion so I feel everyone will at some point use it, it could either be built in to fones or uploaded as an app, but I'm not technically minded and don't make machinery or circuit boards so I only have the idea, the genisis so to speak! But need to know who to speak to to make it happen? Do I contact apple? And what if when I tell them my idea they say thanks and make it and I get nothing for it? How do I prove it was my idea? It clearly has not been thought of yet otherwise it would be available now!
