Glitches in iOS 8.0.1 operating system bring frustrations to consumers, reports Bloomberg.

Apple Inc Chief Executive Officer Tim Cook called the introduction of the iPhone 6 and 6 Plus over the weekend 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. It promised a fix soon.
