Changes

In the chapter entitled [[Creating a Simple iPad iOS 4 App (Xcode 4)|Creating a Simple iPad iOS 4 App]] we were able to see an iPad application that we had created running in the iOS iPad Simulator environment bundled with the iOS 4 SDK. Whilst this is fine for most cases, in practice there are a number of areas that cannot be comprehensively tested in the simulator. For example, no matter how hard you shake your computer (not something we actually recommend) or where in the world you move it to, neither the accelerometer nor GPS features will provide real world results within the simulator (though the simulator does have the option to perform a basic virtual shake gesture). If we really want to thoroughly test an iPad application in the real world, therefore, then we need to install the app onto a physical iPad device.
