The Apple iPhone unveiled Tuesday, described as jaw-dropping by one analyst, will be offered exclusively in the United States through Cingular Wireless, both companies announced at the Macworld Conference & Expo in San Francisco.

The iPhone will be available starting in June through Cingular and Apple online and physical stores. The iPhone carries a list price of $500 for a device with a 4GB hard drive or $600 for one with an 8GB hard drive. Those prices require a two-year Cingular service contract at extra cost. Carriers and handset makers usually discount the phone's price from the list price for customers who sign a service contract, but Apple did not reveal the list price of the phone.

Apple, the new corporate name replacing Apple Computer, said the iPhone will be available in Europe in late 2007 and in Asia some time in 2008.

The iPhone will operate on Cingular's EDGE data network based on the GSM wireless platform. The iPhone also supports 802.11b/g Wi-Fi and Bluetooth 2.0 wireless technologies.

The exclusivity agreement between Apple and Cingular was ambiguously described as "multiyear."

"That's one of those terms of the contract that we mutually agreed not to discuss," said Cingular spokesman Mark Siegel.

Although some new phones are initially sold just by one carrier, many of them eventually end up being offered by multiple carriers. But Siegel said this deal is different.

"In today's business environment, a multiyear commitment is a serious one and obviously that shows that we have great faith in Apple and that Apple has great faith in us," he said.

Siegel also emphasized that, contrary to prior speculation, this is not a Mobile Virtual Network Operator (MVNO) arrangement, in which a company leases network access and brands the phone and the service as its own. Given the significance of the phone Apple was developing, "the only way we (Cingular) were going to achieve what we thought we could achieve with this extraordinary device was for it to be a full partnership."

Besides the phone, the device also includes a camera, a video iPod, address book, calendar and other organizer functions, and a Web browser more robust than that available on other smartphones.

"This phone rightfully drops jaws," said Roger Entner, a mobile phone industry analyst with Ovum Ltd. "This is going to raise the bar."
