NEW YORK (AP) — Apple is expected to reveal a digital radio service and changes to the software behind iPhones and iPads on Monday as the company opens its annual conference for software developers. Apple hasn’t said what it will unveil at the Worldwide Developers Conference in San Francisco. But the major announcements are expected during Monday’s keynote presentation. Last year, Apple used the conference to announce its own mapping service, better integration with social networks and improvements to virtual assistant Siri. It also announced thinner MacBooks with high-resolution screens. The conference runs through Friday.

This year, Apple is expected to show off a simplified look on iPhones and iPads. If the speculation is correct, it would be the most radical design change since the iPhone made its debut in 2007, showing consumers that phones could do much more than make calls and exchange messages.
