I'm trying to figure out where to go to pick up 2 iPhone 5's. I have one being shipped to my home. I know that the Apple store is my best bet, but the wait time will be horrible unless I show up very, very early. What are my chances at an AT&T store? Should I call a day ahead and ask how much stock they plan on having, would they know? In recent years AT&T store have had very little stock which is why I'm asking.
