iPhone Sales are Brisk

Tulsa, OK – Apple Inc.'s newest iPhone is seling briskly around the world today, including here in Tulsa.

Thousands have been lining up outside stores to snag one -- amid concerns of supply shortages.

Some stores -- including ones in Tokyo, Miami and San Francisco -- sold out within hours as the iPhone 4 went on sale in the U.S., France, Germany, the U.K. and Japan.

A police officer in Washington, D.C., who pre-ordered an iPhone, smiled and proudly held it up for the crowd to see as he left the newly opened Apple store in the Georgetown neighborhood. Sean Hill said he's "like a kid in a candy store" -- and that he'd probably "spend all morning playing with it."

More than 600,000 people had rushed to pre-order iPhones on the first day they were available.

It prompted Apple and its exclusive wireless partner in the U.S., AT&T, to stop taking orders for pickup or shipment by today's launch. On Apple's website, new orders weren't promised for delivery until July 14.
