Some months ago I remember reading that Apple was denying iPhoneApps that were simple wrappers for Safari. As we have come to accept Apple keeps many of these decisions close to the vest.This evening I was logging into Facebook when I saw the Facebook App partially render itself and then a number of Safari controls were displayed. In order to test my theory out I brought up Facebook with the actual Safari App on on the phone. And the results were identical except for the toolbar the bottom of the screen.So now what’s the difference between creating a desktop link to Facebook and actually using their app?More importantly, what’s the point? How much more information does Facebook receive because I downloaded the app versus using it natively in Safari?
