Happened by the Apple store last night at our nearby mall. Almost no wait (line gone by about 7:30). Plenty in stock. Many people purchasing. We observed that many seemed young and perhaps w/o means to pay. Asked the sales person about this - he said everyone was buying 2 and planned to sell one on Ebay to pay for the other. Methinks many will be disappointed. I only hope they list with a reserve high enough that they can return the iphones.
FWIW, I did play with one, IMHO, not worth the move from TMO.
