Sorry, I was doing it from memory and the first digit of the four seems 
to be the SIM vendor so I shouldn't have said beginning with a  2.
The 71324 is the SKU for the AT&T latest UICC.
The 4021 is the Vendor and Version number.
Based at looking at some cards the vendor numbers are
    2 - G&D
    3 - Gemalto
    4 - Oberthur

I have access to a tool monitoring the communication between the SIM and 
the handset so I will be able to investigate this later.
Unfortunately, they haven't charged my credit card yet so at best I will 
not have a device for a couple of weeks and I only have access to G&D 
and Gemalto UICCs.

Hopefully someone else can help you in the meantime.

It'll be a bit of a blow if the phone won't work with the largest US GSM 
operators SIM cards!
