Stood in line for three and a half hours yesterday at my Apple store just to see if I could even get my hands on any model. The employees insisted that anyone near my position in line for sure wouldn't be getting a ticket, but I stood around anyways.
After a fight and cutting ensued, I got to the front of the line and all they had left was one 64 3G for Verizon, I was hoping to get AT&T. I may exchange later, as I get good enough coverage with AT&T wherever I'd be bringing my iPad. Still not sure though yet, as Verizon 3G seems speedy enough for me.
