iPhone 5, new iPod, may leave some cars in the dust

Apple Inc. unveiled a new version of the iPhone that boasts a bigger screen, faster chip and access to speedier wireless networks, an overhaul aimed at widening its lead over Samsung Electronics Co. and Google Inc. in the $219.1 billion smartphone market.

The thinner, lighter device is called iPhone 5 and costs $199 to $399. It sports a casing made of glass and aluminum, a chip that can process commands more swiftly and a four-inch screen -- compared with 3.5 inches on the earlier models. Apple also revamped its mobile software, adding three-dimensional mapping, closer integration with Facebook Inc. and improvements on the Siri voice-recognition feature.
