Bloomberg reports that the production rate of the fastest selling iPhone yet has slowed down as Apple has increased quality control at Foxconn. At the moment, it is extremely hard to buy an iPhone 5 with new unlocked versions starting at $1,000 on eBay and other sites. Some customers who got the iPhone 5 noticed that the device was damaged and some found the device to be extremely prone to scratches.

To prevent this from happening, senior executives at Apple have instructed Foxconn to tighten quality standards and increase quality-control. Apple sold 5 million iPhone 5s within just three days of its availability. Phil Schiller, Apple VP notified customers a few days back that it is normal for aluminum devices to scratch and chip.
