Reserved at store on April 30 when notified they'd sold out. Received e-mail today that it is there waiting for me to pick up.
Ordered on-line May 1, when found out I could not use Apple gift card ⚠ in conjunction with debit card for in-store purchase. Have been tracking on-line ever since; left China on the 12th, hit Hong Kong, just left Memphis. Est. delivery date still says the 17th--it was originally the 11th-15th--but I've read these estimates are incorrect, perhaps by design (theft prevention, etc.) I'm hoping to be pleasantly surprised tomorrow or Saturday.
FWIW, I originally got the wifi, then returned for the 3G. These are so amazing that I've been missing it ever since. It's every bit as game-changing as he said, and worth waiting for.
