I have a question for those who have preordered an iPhone from an AT&T store in the past: Have you had to wait in a line to pick it up the first day? How long was the line? When did you have to start lining up to ensure you got your iPhone on the first day? I'm asking because I pre-ordered at my local Sprint store (they're doing early pre-orders). I've seen coverage of the insane lines at Apple Stores when a new iPhone or iPad drops, but never a word about what it's like at a phone retailer. I would ask Verizon customers, but I remember reading that the Verizon response was rather muted since the iPhone 4 had already been available for quite a few months before release on Verizon. Any insight anyone can give will be much appreciated.
