title: BlackBerry use of the simulators
body: <p>Hallo,</p>
  
  <p>on the BlackBerry homepage you can download different simulators for every different model. There are a lot fo simulators there...</p>
  
  <p>My question is, how do you develop BlackBerry applications:</p>
  
  <ol>
  <li>do you use the simulators - can you relay on them. If an application works on the simulator, does it works 1:1 on the phone?</li>
  <li>Do you develop for every model a different UI, as the screensize is different?</li>
  </ol>
  
  <p>Thanks you very much for your replay?</p>
