is midnight a good time to show up at at&t to get two 32gb's? is that far enough ahead to be pretty much garanteed two of them? i know this release is probley going to be the biggest ever for apple so im just a little worried is all. and at&t will have some set aside for people doing walk ins on the 24th right? just making sure there entire stock isnt just for the preorders picking up on the 25th or something. thanks
