this might sound like the stupidest question ever asked here.. but i dont get the APPS.. I mean, i looked through them on the apple website, and its all good and great, but they arent actually applications that you download to your phone right?? they are just websites that work really well with your iphone correct?? I mean, i would LOVE to have an application that works like the calculator on the phone, but it calculates gas mileage. I SAW a gas mileage app, but its just a website that calculates it for you, notsomething that sits in the home tray that you can use without accessing the net.. Or am i wrong, did i miss somewhere where i could download that.. so are there ANY program type things that you can download to your phone and use it like software..
