I'm back with another newbie question: The app store shows apps for the iPad and iPhone when visiting the store on my iPad. Can the iPad run both or is it recommended to only run iPad apps?
The iPad can run both, if it has a + next to it in the app store, then it means it will run optimised on both. If it's an iPhone app without the plus, then it will run windowed on the iPad, which you can expand up to almost fill the screen.
