I ended up ordering at 2am. Selected the space gray 128 AT&T iPad air. Got the email at around 5am that it was ready to pick up. Showed up at the Apple Green Hills store at around 8am. They had already started selling to customers. I walked right in since I had ordered for pickup and was out the store by 815am.
One strange thing was that i ordered the black iPad case but the online Apple store shipped the case instead of allowing me to pick up. I ended up just purchasing the case in store and will return the case shipped when it arrives.
