Apple unveils latest mobile software

Apple has unveiled the next version of its mobile software, adding maps and integration with Facebook to extend its lead over Google in the market for handheld devices and downloadable applications.

Apple’s iOS 6 will have more than 200 new features, including turn-by-turn navigation and tools that make it easier to access Facebook from iPhones and iPads.

The company also upgraded its MacBook computers, adding faster chips and sharper displays to the high-end Pro model months before competing devices with Microsoft’s Windows arrive on store shelves.
