title: Test app on a jailbreak iPhone
body: <p>I registered to Apple Developer program and paid 99$. 
  Now I want to test my application on different iPhones. My friend has jailbreak iPhone so i wanted to know if I can use it to test the application.
  1. Is that okay with Apple? i mean is it a violation of the developer program terms?
  2. Can it undo the jailbreak on the device? </p>
