Lines continue at the Apple Store

It's 7:45am and I'm outside of my local (Philadelphia Area) Apple Store. The store doesn't open until 10am yet there are already a dozen or so standing in line anxiously awaiting the store open just over 2 hours from now to get their hands on a shiny new 3G iPhone. It's unknown when the shipment will arrive and how many phones will be on it. These folks don't even know what capacity phones will be available. Never the less, they wait with anticipation to be some of the lucky few to have a phone in the first few days of the launch event. I'm going to assume lines like the one I'm witnessing are beginning to form across the country. Any guess as to when they'll sell their 2nd million phones??
