As I’m sure you already know, Apple doesn’t actually manufacturer its own products. Steve Jobs and the rest of the Cupertino crew turned to Foxconn to make its iPhone, but it seems that some quality control issues are starting to come up with the increased demand for production.

As it stands, Foxconn of Taiwan is said to be pumping out somewhere in the neighborhood of 800,000 iPhones each and every week. If Foxconn were to maintain this schedule for a whole year, we’d be looking at over 40 million iPhones! Foxconn had to ramp up production on the iPhone 3G “above current full capacity” because Apple is rapidly expanding the iPhone into another 50 more countries before the year is out.

That’s all well and good, but it seems that this increased production is causing “some concerns with quality control.” No details have been released as to any specific problems, but we do hear that iPhone cracks are a common occurrence.
