It's the store I worked at, so I have some vague idea...
iPad launch, for comparison, had people queuing up outside the door by HMV, and the door by Cafe Nero. At around 7am, the doors by Cafe Nero were opened, allowing people to enter the Arndale. A queue then forms around the railings outside the Apple Store, and loops back around on itself.
When I drove into Manchester at around 6:45am, there were maybe 30 people outside of the HMV entrance, and around 10 outside the Nero entrance.
I expect iPhone 4 launch to be bigger though. Hope it helps.![]()
Cheers!
