The first batch of iPhone 5 smartphones has already sold out on Apple's website with delivery times to climb quickly. Apple began taking online orders for the phone on Friday, promising delivery by next Friday, when the new phone also goes on sale in stores. Soon Apple Store's servers became overwhelmed by waiting online users. Withion four hours, the expected delivery time had grown to two weeks.

The best chance of getting an iPhone 5 on September 21 looks likely to be getting down to a physical Apple store.

AT&T and Sprint are still promising delivery by next Friday, while Verizon Wireless is promising delivery on Sept. 26.
