Lost iPhone 3 in taxi Friday night/Saturday morning

I seem to have left my iPhone 3 in the back of a taxi in Dublin south city centre, on the early morning of July 13th. It was dead and it has recently been having a lot of difficulty charging so if you try and charge it, it probably won't come on for hours. It's definitely on the way out so will be no good to whoever finds it, I need to get a new one anyway but I really want my pics and contacts off it. Thank you
