As Apple (AAPL) unveiled its newest iPhone model - branded "the future of the smartphone", with its full-display design and an arsenal of features such as seamless support for facial recognition - a number of Hongkongers are already planning to make money reselling the devices across borders.

Hong Kong, mainland China and Taiwan are among the first of 55 countries and territories where one can pre-order the most expensive iPhone ever, the iPhone X (pronounced "iPhone 10"), from October 27 at a minimum price of HK$8,588 in the city and 8,388 yuan (HK$10,038) on the mainland.

But the returns from reselling may not be as big as they used to be, as Apple products are now rolled out on the mainland at the same time as Hong Kong, traders said.

The launch of the first iPhone, 10 years ago, created a thriving "grey market" in Hong Kong.

The same devices are usually more than 10 percent cheaper in the city than on the mainland thanks to the free port's zero-duty treatment for most electronic products.

That allowed many local dealers to make a living by exploiting the price difference for iPhone products between the two sides. The first few days of a product launch often saw grey-market prices double the usual retail price, due to the limited supply through mainstream channels on the mainland.

Dealers at Sin Tat Plaza in Mong Kok - where store owners collect iPhones from individual sellers and resell most of them to mainland buyers - said they believed the iPhone X had more market potential despite the high cost, with some looking for a 50 percent premium in the first week it is on sale.

"Price has never been a big problem for those who use Apple products," Samuel Lau, who owns an electronic gadget shop at the plaza, said.

He said he expected dealers to earn about HK$3,000 on a basic iPhone X in the first few weeks.

Another dealer, Lo Lau, said he believed the iPhone X could sell at a 50 percent premium in the first few days but expected the price to drop to the standard retail price within three weeks.

The iPhone X's new features mark a leap forward from previous models, whose appearance had not changed much in the past two years.

It boasts an all-screen display built with an 5.8-inch OLED touch screen that Apple has branded a "super retina display". The home button has been replaced with a simple swipe motion to open and close applications.

Users can securely unlock the iPhone using its sophisticated Face ID function. Face ID, which works only when the user looks at the iPhone, is also designed so as not to be fooled by photos or masks, increasing security for facial recognition applications, the maker has claimed.

While Apple fans are thrilled by the new features of the 10th-anniversary iPhone, critics have said it is not an evolution of smartphones. Some have said its edge-to-edge screen looks boxed in compared to the latest Samsung handsets, which also have face-recognition functions.

Apple also updated its iPhone 7 and 7 Plus models with the new iPhone 8 and 8 Plus models featuring glass and aluminium cases, as well as support for wireless charging and augmented reality. These handsets will be available for pre-order in more than 25 countries and territories on Friday and in stores from September 22.

Dealers expect iPhone X sales to be high partly thanks to the city's large number of iPhone 6 and 6s users, who are ready to upgrade their smartphones after using them for two to three years, shop owner Wong Kwok-fai said.

But it would be much harder to earn a profit trading iPhone 8 and 8 Plus models, which feature only a slight quality improvement over the previous models, he said.
