Cook goes to China

Cook traveled to China for -- well, Apple never officially said why. But speculation focused on the two carriers which offered Apple's handset, China Telecom and China Unicom. He might also have been in town to try to work out a deal with China Mobile.

But beyond that, Cook had some PR spade work to do as a result of the ongoing outcry over worker conditions at Chinese factories which make Apple products. Indeed, Cook did pay a visit to the new Foxconn manufacturing plant for the iPhone in Zhengzhou, China, which employs 120,000 people.
