I plan on getting the iPhone 4S right on October 14 (I am due for an upgrade and my current phone is old/barely operational) and I had a few questions on how I can buy. Can I pre-order online? Will I be able to pick up my pre-order at any AT&T store/can I specify which store I'd like to pick it up at? Should I purchase through the Apple store or AT&T store? Thanks for all the help!
