The folks over at macrumors.com are reporting that Apple and AT&T have begun updating order statuses and providing UPS tracking numbers to the customers for their iPhone 3G S orders. If ordered from Apple, shipments are being sent from Shenzhen, China and are due for delivery on Friday, the official launch date for the iPhone 3G S. If ordered from AT&T, the order status appears as “in progress” and have been assigned tracking numbers, however, the shipments do not appear to have yet been picked up by UPS.

Visible signs of AT&T’s and Apple’s preparations for the launch of the new iPhone, as well as the corresponding release of iPhone OS 3.0 for older devices this Wednesday, have begun appearing in the days leading up to the new releases. Over the weekend, AT&T also sold out of its initial iPhone 3G S pre-order allotment, meaning that those who wish to obtain an iPhone 3G S from AT&T on launch day will have to do so in-person at an AT&T retail store.
