Moves by Apple to control crowds at Chinese stores (due to concerns of violence and scalpers) and an increase in the number of points of sale, as well as a stronger online and in-store reservation system may be fooling some analysts into thinking that the iPhone 5 is seeing weaker demand than forecast. Analysts from UBS and Jeffries cut their estimates on iPhone sales on Friday, sending the stock plummeting four percent to close at $509.79, a ten-month low. The lack of long line-ups that had been seen with previous iPhone launches may be making investors nervous.
