My iphone 4s that I got at the beginning of January, I had a weird moment and smelt the bottom of my iphone, where the charger slot is. It has a bizarre smell like not burning but a very prominent plastic smell, the end of the charger has this smell too. My mothers ipad and her charger do not have this smell but are significantly older. I've read a few threads of iphones magically combusting up into flames and thought I might ask. Do your new iphones have this smell?
