Just ordered mine through Best Buy on AT&T next. Online showed all the others were not in stock, and this one didn't show the same stuff. So I figured I cancel my order with Apple which I did yesterday and ordered it today with Best Buy. As I may get it faster. I had to use our other line to do the upgrade as the one I did with Apple hasn't reset yet since I canceled it. No idea how long that will take.
With the mamp 20k charger too. Next forces them to charge you the normal price and not the best buy price.
