You're new to iPhone, right?

Let's recommend a tutorial post to you, take a good look.

Identify whether the iPhone 4 is a refurbished machine:

Click on the settings--General--About the machine, there is a serial number, the third digit is the year of production of the mobile phone, and the fourth and fifth digits are the weeks of machine production, for example, 111 is the machine of 11 years and 11 weeks. Based on this, we can calculate how long the machine you bought at that time has been in production. Another item is the model, if the last two letters are CH means that the machine is licensed in the mainland, if it is ZP means that it is licensed in Hong Kong;

Under the dialing interface, press "*" in turn, this set of numbers must be exactly the same as the numbers on the mobile phone card slot, in order to verify the identity;

The trademark information marked on the back cover of the iphone4, the machine with the word Chinese represents the licensed goods in the mainland, and the representative with the word China is licensed goods in Hong Kong;

Log in to Apple's official website and enter the serial number to activate, and the third checkmark shows the expiration date of the warranty period of the machine, which is pushed forward by one year, which is the time when you purchased the machine;

After disassembling the new machine, you can see that there will be a white sticker on the screw. If not, it's probably a refurbished machine.

1. If you buy 11 years, the probability of refurbished machine is smaller.

2. Parallel cargo planes are all boxes separated and transported to China, so they have been dismantled, unless there are special requirements for the Hong Kong version of the machine.

3. Please identify a knowledgeable friend, this depends on experience.

4, where to 10 yards, generally is the fuselage and the system of the serial code this is two yards in one, and then the same is the same as the packaging box is three yards, at most is the Hong Kong bank has a Hong Kong invoice, the serial number and the previous one is the same is four yards, where else can there be a code on?

Jailbreak is not necessarily used, of course, it is best to check whether it is a recent shipment through the code behind the machine.

In fact, it's best not to break from prison, buy unopened envelopes and come back to pay for them.

Chinese will be written on the back of the licensed goods.
