SAN FRANCISCO – Apple held an event in San Francisco during which it announced a new iPhone, capable of faster data speeds and sporting a taller screen. It also unveiled new iTunes software and new iPod devices.

The iPhone 5 will go on sale next week. It will work with fourth-generation, or 4G, cellular networks, something Samsung’s Galaxy S III and many other iPhone rivals already do.

Apple Inc. also is updating its phone software and will ditch Google Inc.’s mapping service for its own. The two have become rivals as Google promotes phones running its Android operating system.
