Ordered yesterday evening after returning a couple iPad Airs. 5-10 days for 128GB AT&T. No change in my status so far. The Bay Area Apple Stores seem to have 64GB Cellular (all carriers) available for in store pick up. No 128GB AT&T in my area and I've been checking hourly.
There is one earlier post that a 128GB LTE was preparing for shipping. Which is good news because this model was originally listed and still listed at 5-10 business days.
I would do an in store pick up for a 64GB LTE and manage my data better. However, I purchased these on multiple gift cards, which the zero value cards have been destroyed. I called Apple, and it seems like there is nothing that can be done other than waiting to receive the two 128GB LTE. Worse was the Apple Store blue shirt actually took the zero value cards and destroyed them once my order was placed (as a favor). He said the cards were no longer needed. Never mentioned that order cancellation would require each individual card.
