I've been paying attention to your problem, so I'll tell you what I know for your reference. I went to that store last week and was surprised to see that the fourth generation was available. The price of mobile phone is the same, 16GB is 4999, but the price has increased by 980. The clerk explained that their package price includes card cutting service and downloading related software services. At that time, I also doubted whether it was genuine, so I called Apple at 4006668800. The customer service said that it is also an authorized dealership of Apple, but it is not authorized to sell mobile phones, indicating that their goods were not purchased through formal channels. As for whether the goods are genuine or not, the customer service expressed uncertainty. It is recommended to order in Apple official website online store or physical store. Regarding the price increase of 980, the customer service said it was a disguised price increase. Because the card cutting service is free in SIM card operators, and Apple has tens of thousands of applications that can be downloaded for free.
In addition, the customer service also told me that if it is Unicom version, there may be a LOGO on the back. If it is genuine, the words on the back must also be simplified words, and there is a triple A anti-counterfeiting mark.
That's all. I hope it works for you.
Finally, personally, I don't want to buy it there even if it is licensed. Wangjing Jiamao also has an Apple authorized dealership, which is also booked at a high price, because authorized dealerships do not sell mobile phones. Only Apple's two direct stores can sell them, and you must make a reservation in a physical store in official website to buy them. Fortunately, under the guidance of customer service, I successfully ordered one in official website Apple Online Store yesterday, with online banking payment and delivery in one to two weeks. More practical, hehe. The online booking system is not open every day. If you want to book online, you must log in at 90 o'clock every morning to see if you can order.
