Feature Request: disclosing PhoneId (aka UDID in iOS)

[adams-family]

Any plans on creating a public property disclosing the phone's unique ID (UDID in iOS)?

I noticed that the GetnerateAppId() method is capable of determining the phone ID, whoever it always appends a random GUID. I'm interested in the UDID without the extra random GUID.

Also, if it's not a good idea, I'm happy to hear why.
