I'm a newbie so forgive me if this is a topic that's been done to death in the past. I've cancelled my order on the Apple store for an iPad Air 2, and was thinking about ordering it through AT&T as they're offering $100 if you sign a 2 year contract. The device fee to add it to my mobile share plan is $10 either way, contract or not, and I was planning on adding it to my existing mobile share plan. So is there any reason NOT to order from AT&T? I could basically get a 'free' upgrade to the 128GB version instead of the 64GB version I had ordered. Will these iPads come with the Apple sim from AT&T (do they usually come in the original Apple packaging?) or do AT&T open them and insert their sim? I'm not too worried about waiting an extra week or two as I've managed until now with my iPad 2 bought on launch week!
