Build 2013 Nokia Lumia 920.1 Phone Dev Kit

Hey,

I just received a Lumia 920.1 from one of the WP sessions here at Build. What's the difference between a Dev phone and also difference between 920.3 (last year's Build giveaway) and 920.1 (the one I received today)?


Thanks. I've only developed on retail phones (but still given from MSFT).

Going to move this over to the developers forum so that one of the devs can see it and might be able to give you an answer.
