title: consistany of device.uuid in phonegap android
body: <p>I am using phonegap for my Hybrid Moble app.The user will have a user name and password to enter into this app.A particular user can use only one device to login to this app.For this i am using the device.uuid for getting the user device unuquily and based on that,that particular user is only allowed to login from that particular device.Now i have three doubts.</p>
  
  <ul>
  <li>Will the device.uuid changes on changing the sim card?</li>
  <li>Will the device.uuid changes on re booting the device?</li>
  <li>Will the device.uuid changes on changing the wifi network?</li>
  <li>Will the device.uuid changes on Upgrading or changing the OS version(Android)?
  -And how consistend it is?</li>
  </ul>
  
  <p>Thanks a  lot</p>
