Apple on Thursday disclosed its iPhone sales dipped slightly during the holiday-season quarter, signaling a sluggish start to the trendsetting company’s effort to catch up to the rest of Big Tech in the race to bring artificial intelligence to the masses.

Apple's latest iPhones are flying off the shelves in some markets, and not in others. Apple CEO Tim Cook says this all comes down to where Apple Intelligence is available, and where it isn't.

The tech giant’s sales of apps and services helped profit grow 7 percent from a year ago, even as the company contended with slumping sales in China.
