Foxconn can't keep up with the demand

"It's not easy to make the iPhones. We are falling short of meeting the huge demand", Foxconn's chairman Terry Gou is cited in several articles in saying. Although he did not say which of the models he was referring to. However, given the fact that the iPhone5 has a delivering time of 3-4 weeks - it can be safely assumed that it is the latest Apple product that is causing problems.
