There is no means for you to recommend Android phone over iPhone for a business because I believe that this too kind of phones combined with the very good for any business.I will recommend you an android phone over iphone and your intended business doesn't you to spend too heavy on phone just for the sake of it. If what you mean by steel (is an alloy of iron and carbon), I don't know what special thing an iphone would do that a simple android won't. Safe cost and use the money up in other things
