(AP) -- PC maker Dell Inc. is working on a smart phone for China Mobile Ltd., China's biggest cell phone carrier.
Rumors of a Dell phone date at least to 2007. Now Dell spokesman Matthew Parretta says the company showed a "proof of concept mobile device prototype" at an event hosted by China Mobile in Beijing on Monday.
Parretta would not say when a Dell phone would be ready for use, or what operating system it might have.
China Unicom, the country's second-largest wireless carrier, is in talks with Apple Inc. about selling the iPhone in China.
