AP reports that Apple Inc. is putting on sale unlocked iPhone 3G in Hong Kong, allowing people to use it with any mobile phone carrier.

The move seems to depart from its previous strategy of introducing the popular device capable of 3G, or third-generation, through specific service providers in 22 nations.

On its Hong Kong Web site, the Cupertino, Calif.-based company is advertising direct sales of iPhone 3G, saying people can “buy directly from Apple” and choose their own carrier.

“Phone 3G purchased at the Apple Online Store can be activated with any wireless carrier,” it said on the site.

Offering free shipping, the 8-gigabyte phone goes for $5,400 Hong Kong dollars ($695) while the 16-gigabyte version costs HK$6,200 ($798).
