You can remove the lighter housing quite easily. Haven't done it for a while, but just remove the glove box and then there's a bracket behind the thing that unscrews. Dead easy. With it out - or still in - you will be able to bend the contacts back in a little to improve the 'grip'. It may not have been touched for years and was designed to fit snugly on a metal lighter. Plastic stuff won't form an interference fit nearly so well. Alternatively, run a wire from behind that area under the carpets to the ashtray area between the seats and put a near little wire for your iphone there. Also dead easy.
