Apple has started shipping iPhone 4 units to customers who pre-ordered the device last week. According to shipment details seen by one iLounge editor, the phones appear to be shipping directly out of Shenzhen, China. Based on reports from iLounge readers, some shipping estimates list June 23 instead of June 24; however, Apple has in the past halted shipments that would have arrived earlier in order to coincide with its pre-announced launch date. Apple will officially launch the iPhone 4 in the U.S., U.K., France, Germany, and Japan on June 24.
Update: AT&T has also started emailing iPhone 4 pre-order customers shipment notifications and tracking numbers.
