The official Xinhua News Agency says hundreds more were seized during three separate busts Thursday through Saturday in Hong Kong, including from men with a speedboat who were loading contraband onto a wooden sampan-style boat in a mangrove.
Xinhua says the latest seizure was from the luggage of two passengers arriving at the Shanghai airport from Tokyo, one of them Chinese and one of them Japanese.
Nearly 700 more of the phones have been confiscated individually from passengers who did not declare them.

Lured by the promise of profit from smuggling the new iPhones into China, opportunists joined the thousands of Apple Inc fans lining up to buy the devices as they were launched on Friday across Asia.

Regulatory hurdles mean the iPhone 6 and the larger iPhone 6 Plus won't be available soon in China, the world's biggest smartphone market where Apple products are popular.
Benefitting from the delay were many people in Singapore, Hong Kong and Australia, who said they were buying as many iPhones as they could specifically for resale in China.
Justin Leung, a 28-year-old financial planner from Hong Kong, said he paid his friends in Japan to buy iPhones, which he plans to sell in mainland China. Leung said he had set out to buy 35 iPhones from Tokyo, but he and his friends only managed to get a hold of 25 units.
At an Apple store in Tokyo's upmarket Omotesando boulevard, another Chinese man said he had paid a group of Japanese to buy iPhones on his behalf. He declined to identify himself, but was one of several Chinese buyers queuing up at the store on Friday.
Apple representatives could not immediately be reached to comment on the practice.
China has granted the new iPhone approval for use on domestic frequencies, but the phone cannot be sold in China until a key network license is granted, the official Xinhua news agency said on Thursday. It did not say how long that would take.
The delay had given smugglers reason to cheer, with many Hong Kong residents racing to pre-order the phone online.
Such is the appeal of the iPhone in China that in Singapore, several people said they were getting paid to queue up to buy the devices with the intent of reselling them to dealers.
