What is the difference between the iPad Mini model numbers A1454 and A1455? Apple lists the iPad mini models on the Identifying iPad models web page and lists two cellular models:


A1454 on the iPad mini Wi-Fi + Cellular
A1455 on the iPad mini Wi-Fi + Cellular (MM)


I can't seem to find a mapping between these models and the iPads for sale by Apple since they list the intended carrier and a different part number like MD534LL/A. Apple has a nice LTE page for iPhones, but I can't find the iPad page.

In the US, the Black 16 GB iPad Mini (2012) has the following parts for our three cellular carriers:


AT&amp;T - MD534LL/A
Sprint - ME215LL/A
Verizon - MD540LL/A


None of the Apple LTE articles seem to be updated yet for the 4th Generation iPad with LTE or the iPad Mini with LTE so I'm stumped at the moment. What is the difference between the Cellular A1454 model and the Cellular (MM) A1455 model?
The comparable page you're looking for is: http://www.apple.com/ipad/LTE/. A1454 is used for AT&amp;T and similar Canadian networks only, while Sprint, Verizon and overseas carriers use A1455.
