title: Read APN settings (Not write)
body: <p>I am developing an android application which will send MMS.
  But to send mms in need to read APN settings of user.
  I searched on internet. But the solution i get is by using Content Provider with uri of </p>
  
  <p><i><b>"content://telephony/carriers/preferapn"</b></i>. </p>
  
  <p>But when ever i call it using </p>
  
  <p><i><b>Cursor c = this.getContentResolver().query("content://telephony/carriers/preferapn",null,null,null,null);</i></b></p>
  
  <p>It is throwing exception of "No permission to write APN settings".
  But i only want to read. Not write.
  Please tell me how to read apn settings. Only read, Not write.
  I am developing application which will support SDK 15 and above.</p>
