Got to my mall around 6:30 and I'd say around 500 people were lined up. They had two separate lines for those who pre-ordered and those who did not. They were taking people who reserved first and then every once in awhile some from the walk-ins. I waited in line for about 3 and a half hours till I got in. The whole process took about 10 minutes.
This phone is seriously amazing. The first thing I noticed when I first held it was how strong the build felt. It made the 3GS feel like a cheap toy. The display is AMAZING. Loving it so far. OS4 is so smooth.
