The numbers defied some of the market's low-ball estimates, and suggest the technology giant still has cachet with consumers as it fends off a stiff challenge from Samsung.
Apple fanatics snapped up the new 5c and 5s models in droves, with lines snaking around Apple's iconic retail stores last week. Some ebullient fans even camped out overnight, in order to be the first to get a hold of the new device.

"The demand for the new iPhones has been incredible, and while we've sold out of our initial supply of iPhone 5s, stores continue to receive new iPhone shipments regularly," Apple CEO Tim Cook said in a statement.
The market's estimates were off for Apple sales because the tech company combined sales of the 5c and 5s models, Gene Munster, an analyst at Piper Jaffray, told the "Fast Money Halftime Report."
"The way they announced that number was a little bit different than they typically do. When you back out that channel fill of the 5c, the number was pretty much right in line with about 5.5 million, which is positive because it's up from 5 million a year ago. But you need to kind of put that 9 million into context and I don't think the Street was as off as maybe it looks at first blush," said Munster, who is currently has an 'overweight' rating on the stock with a price target of $640 a share.
