Apple's iPhone 6 & 6 Plus off to best start in iPhone history

Calling it the biggest and most successful iPhone launch ever, Apple Chief Executive Tim Cook revealed the success at a special event in Cupertino, Calif., on Thursday. Though he boasted of high sales, Cook declined to get into specifics, simply saying that it was the best first-month sales ever.

"And I don't mean by a little," Cook said. "By a lot. A whole lot."

Sales for the first two weeks of iPhone 6 and iPhone 6 Plus will be seen in Apple's results for the September quarter, which will be revealed next Tuesday.
