China’s second biggest mobile phone -firm known as Unicom (Hong Kong) Ltd., declined the most in more than two months seen in Hong Kong trading after stating that it’s profit last year plummeted more than fifty percent.

China Unicom Company Vice President, Li Gang declared the sale of the first shipment of the iPhone 4 in China. The official launch of the iPhone 4 in China was done, on Saturday.

This Company is the sole mobile carrier for the iPhone 4 in China and has said that as many as 100,000 iPhone 4s have been sold in the market within four days of the launch of the device, in China.

Last year in October, the China Unicom Ltd. offered the sale of Apple’s iPhone. It is the only Company in China, which is selling iPhones’ units.

On Friday, the Company declared that the smartphone will be available with Wi-Fi system from Monday onwards, on eight-gigabyte version of the iPhone’s 3GS model.

Swedish telecoms equipment group Ericsson is reported to have announced deals with China Mobile and China Unicom worth a combined $1.8bn (£1.2bn).

In view of a major discouragement hitting the company in its fourth-quarter results, China Unicom is now focusing on enhancing its 3G customer base, this year. It considers this expansion as big source of growth.

In a Tuesday statement, China Unicom’s Chairman Chang Xiaobing said that the carrier, which began offering the popular Apple iPhone in China last week after its October 1 launch of 3G services, had already signed up over one million 3G subscribers by the end of October.

As a result of its August-signed three-year deal with Apple, China Unicom is set to commence the sale of the popular iPhone in the country in October. The touch-screen handset will be available at a retail price of nearly 5,000 yuan - though the company is yet to disclose details about the models that will be available.

According UBS analyst, Maynard Um, the Friday-announced deal between Apple and China Unicom will likely bring about the addition of nearly one million iPhones to Apple's sales during its fiscal 2010, after China Unicom starts selling iPhones in the 2009 fourth quarter.
