This is all I want with any future iphone - a dual sim option. Samsung does it, why can't Apple? I travel a lot and am sick and tired of carrying around 3 phones that rattle around and take up valuable space - two iphones and one cheap nokia for each country's sim. I know builder's with 3 phones. Business men. Etc. Not everyone wants to be bothered at night on a business phone and today people use mobiles more and more, land phones less and less. PLEASE APPLE - introduce a dual SIM model, or better still, why don't you become innovative, and introduce a triple SIM option? I am on the verge of decamping to your competitors...
