Question

Is there a way that I can uniquely identify the windows phone device that my app is running on? Is there a windows phone device ID or something?

Answer 1

Try:

DeviceExtendedProperties.GetValue("DeviceUniqueId")

Answer 2

object uniqueID;
if (Microsoft.Phone.Info.DeviceExtendedProperties.TryGetValue("DeviceUniqueId", out uniqueID)==true) {
  byte[]bID=(byte[])uniqueID;
  string deviceID=Convert.ToBase64String(bID);   // There you go
}

Answer 3

Or you can use a globally unique identifier (GUID) in general http://msdn.microsoft.com/en-us/library/system.guid.aspx And save that ID on local storage.

deviceID = Guid.NewGuid();
IsolatedStorageSettings.ApplicationSettings["DeviceId"] = deviceID;
