title: Do I have to buy phone service to write applications for android/iphone?
body: <p>I am interested in building applications for mobile devices, but concerned about the cost of having multiple lines of service. I would like to be able to test applications on multiple devices with varying screen resolutions without having to always use an emulator.</p>
  
  <p>Will I be able to get by on new-or-used devices for which I have not purchased phone service?</p>
