Will there be 6 different models, or will it just be 3 that have different sizes, all 3 have a 3G card inside but only the '3G model' is the one that is activated, because to be honest it would be much better for Apple to just make 3 with all of them having the 3G card so that you can choose to have it activated (with 2 year contract of course) and if you choose the one 'without 3G' then the card just isn't activated, wouldn't this be much simpler than having 6 different models? Much confusing...
