BERKELEY, Calif. (AP) — Apple has agreed to let developers of iPhone apps email their users about cheaper ways to pay for digital subscriptions and media by circumventing a commission system that generates billions of dollars annually for the iPhone maker. The concession announced late Thursday is part of a preliminary settlement of a nearly 2-year-old lawsuit filed on behalf of iPhone app developers in the U.S. It also addresses an issue raised by a federal court judge who is expected to soon issue a decision in a separate case brought by Epic Games, maker of the popular video game Fortnite.
