All three US iPhone carriers are now sold out of iPhone 4S preorders, Bloomberg observes. Verizon and Sprint currently have no stock of 16GB 4S models; AT&T is giving a delivery window of three to four weeks for the hardware, about the same length of time needed for resupplies. In effect the only option for securing a 4S on launch is to appear at a store in person, especially since there are only two shipping days left in the week.
