Hypothetical situation: I make an app for iPhone. In terms of hardware the app needs a GPS, Mobile data, front & rear facing camera and the Accelerometer. Can I run the app in it's iPhone size on an iPad mini and still use all of these features of the device. Also is it possible to see run the app as it would look on a 4s and the 5 separately or will it default to display it as the 5? Cheers.
