I too just got back from a at&t store a few minutes ago, the guy working on my phone told me theirs was still in the back with chains wrapped around them. closing at 4:30 is so they can unpack,prepare, and setup.
they will not be activiting them at the stores, he told me they are just selling them and you activite online only.
there will be 1 police man at his store, he mentioned.
I asked about campers, he said there were rumors but he hasn't seen anything yet.
worth a post I thought.
