Apple announced Tuesday it was launching new iPhones using 5G, the latest smartphone maker to adopt to the new-generation, high-speed wireless networks. "We are going to introduce 5G across our entire lineup of iPhone models," Apple chief executive Tim Cook said at a streamed launch event. "Today is the beginning of a new era for iPhone." The new models include the redesigned iPhone 12, successor to the top-selling iPhone 11 launched last year. rl/bgs
