Cook Goes

Apple Inc. CEO Tim Cook last weekend called the introduction of the iPhone 6 and 6 Plus the "best launch ever." He may have spoken too soon. Just three days after announcing that Apple had sold a record 10 million new iPhones over the opening weekend, Cook was faced with multiple snafus related to the bigger-screen handsets. The company pulled a new mobile software update, dubbed iOS 8.0.1, after the program caused some people to lose cellular service yesterday, and promised a fix soon.
