(MONEY.CNN) — Apple on Wednesday unveiled a thinner, taller, faster iPhone 5 at a highly anticipated event in San Francisco.
The device, which is 18% thinner and 20% lighter than the iPhone 4S, is the thinnest smartphone in the world, according to Apple. With a four-inch screen, the iPhone 5 allows for five rows of apps -- one more than previous versions of the device, which sported a 3.5-inch screen.
Apple said the iPhone 5's processor speed is twice as fast as the previous version, an advance made possible by the company's new "A6" chip.
