Update | Apple reports blockbuster quarter on robust iPhone sales

Apple reported a bigger-than-expected rise in iPhone sales for the holiday quarter, driven by strong demand for the latest version of its flagship smartphone.
Shares of the world’s most valuable listed company were up 2.6 per cent at $124.50 in after-hours trading on Tuesday.
Apple sold 78.29 million iPhones in the first quarter ended December 31, up from 74.78 million last year, marking the first quarterly growth in iPhone sales in a year.
Apple Chief Executive Tim Cook said on a conference call on Tuesday that he expects services revenue to double in the next four years.
“Services obviously continues to be a real success story for them. It’s one of the fastest-growing segments they have, driven largely by the App Store,” said Jackdaw Research analyst Jan Dawson.
