title: What exactly is a Die ID?
body: <p>I am an iOS developer from Germany. Apple has deprecated the UDID access for normal AppStore Apps. So I am searching for a replacement, and finaly came over the DieID. I investigated a bit, but I was not able to figure out if this ID is unique. (The UDID is a Unique Device Identefier, it lets the developer to identify the user, beacause the UDID is unique for every device. The UDID is made from SHA1(serial + IMEI + wifiMac + bluetoothMac) or SHA1(serial + ECID + wifiMac + bluetoothMac). All of these parameters has been made unaccessible in iOS 7 and 8.</p>
  
  <p>Does anyone know if the DieID is unique for every die? I already contacted Samsung, but they didn't replyed yet.</p>
