Hi, I went at 9pm and there was a winding line of about 100 people. I think there were walk-ins or people trying to get support. There as a separate line where security just let in certain people (not sure if they had appointments to pick up their phone). Asked apple guy if they could do anything and he said come back tommorow because they may not even have your phone out yet. I didn't press as I did not have the confirmation email or status update. Now that it says ready to pick up I might go at 7am if anyone can confirm they let you arrive earlier than expected.
