Image from Chinese Engadget siteAT&T is already warning that those making iPhone 3G S pre-orders that they won’t get their handsets on launch.

The US carrier’s internal sales system is asking staff to tell customers that any pre-orders made on Saturday the 13th or later won’t ship on launch and instead will reach retail locations between 7 and 14 days after the order is made, overshooting the release date.

Those who delayed their pre-orders long enough but who still want an iPhone 3G S the same day will have to wait at an AT&T (or Apple) store until regular availability starts at 8 a.m. rather than the 7 a.m. early access time touted earlier this week, Boy Genius hears. Any pre-orders, however, will receive an e-mail once their device is in stock.

Photos of an iPhone 3G S unboxing turned up online long before the official release on June 19th, the images which have now been removed were posted on the Chinese version of Engadget.
