There is a second hand iphone4, ask for identification before starting

Judging from the model, ll is the American version.

The place of origin doesn't make much sense, China is the world's factory.

Second-hand iphone4 should not be a big problem if it is not refurbished, buy second-hand iphone4 don't buy reconstituted, sometimes there will be a white screen. Now teach you how to identify refurbished machines:

1.Mobile phone serial number, like the ID card of the mobile phone, the IMEI number of each machine is unique, generally speaking, you can judge whether a machine is **. Here's how to identify them:

Enter * 06 in the standby state of the mobile phone, a string of numbers displayed by the mobile phone is the serial number of its motherboard, and then look at the IMEI number on the box of the machine and take out the SIM card tray to check the IMEI number on the side and compare the three to see if they are all consistent.

2.When the original mobile phone appears, the mobile phone will have a special sandalwood, which is not pungent and naturally fragrant. The refurbished machine may spray another aroma, which is very unnatural. It can be identified by this method.

3.Generally, after the machine has been used for a long time, there will be dust in the gaps and screw holes of the machine, check whether there is dust in these places to judge how long the machine has been used.

3. The SIM card slot of the second-hand phone will have traces of long-term use, and the card slot will look old (but it is normal to have a little trace when trying the machine).

4. Those who engage in refurbished machines often do not use the original new chassis to refurbish the mobile phone, and they often use the imitation chassis to confuse the real one. Imitation chassis often have a poor feel and even rough workmanship.

5. See how the call quality is, and call a friend to call ** (it is best to use a landline, the effect is good!) If there's a murmur, electric sound, or something like that on a call, don't do it.

The most important thing is to ask the seller to try all the features before paying, such as: call quality, SMS, Internet access, wifi, camera, home button, touch screen, etc.

When the interview is to try Internet access and other functions, but there should be no second-hand mobile phones for the time being.

As far as I know......Hmm......It may not be very accurate My IP3GS is beautiful water The words under the back case are darker.

Actually, second-hand is not very good! (Personal opinion).

Notes:1When the time comes, see if it's jailbroken.,After jailbreaking, he may brush a lot of plug-ins.,So that the performance of the machine itself will be reduced.,Maybe this is one of the reasons for others.,I feel that the performance has decreased.。

2.Take a look at when you bought the machine, whether there has been a maintenance record, and you can find out the relevant information through the serial number or IMEI code to determine whether it was a brand new machine.

3.The price needs to be set according to the machine, this is hard to say, it has not been repaired, and the age of the machine is about a year (from the date of activation) at most about 2k! Personally, I think this **!!

4.If you have to buy it, it is highly recommended to buy it from the Bank of China or the Hong Kong Bank, which is convenient to use in the future.

I hope it will help you, welcome to adopt!!

Second-hand mobile phone, to ask when he bought it, and whether there is a maintenance record, through the iPhone serial number or IMEI code can be found out of the relevant information, to determine whether it was a brand new ** machine, in addition, it is best to buy Hong Kong or Bank of China second-hand, no lock convenient!

I hope it helps you, welcome to adopt!

In fact, second-hand mobile phones are not very good, if the economic situation is okay, you can consider non-second-hand.

The current ** is also around 3650.

When I bought it, I dragged a friend to buy it directly, and the price of 3850 was reduced when I went to change to the black machine.

The iPhone 4 on the market has not been refurbished, but there is a high imitation copycat machine 1, which requires the seller's mobile phone card to use the iPhone 4 to give your mobile phone a ** on the spot to listen to the sound, if the sound is loud and unclear, it may be a copycat. If the earpiece sound is moderate and clear, then it's fine.

2Now that it has been cracked, you'd better connect to the computer to see if you can use the 91 mobile phone assistant to install the software. See if you can show charging. If not, it's definitely a copycat.

3. If the machine is pasted with film, it is best if you can ask to take the film off and carefully see if the machine is scratched, especially the silver edge part and the back.

4. Look at the English text printed under the back of the machine, if there is the word ch, it must be a copycat.

If it's all right, it should be fine.

I saw a lot of them when I bought them in Zhongguancun, and I hope this experience will be useful to you, good luck.

Don't be greedy. If you want to buy, go to a specialty store or Sanlitun.

There is no doubt that the iphone4 has a refurbished machine if it is second-hand. A shell change is also considered a refurbishment, you say?

Pay attention to the production batch number, color difference, signal problems.

PS: I don't know if the Japanese version of the iPhone has a locked version.

If you want to buy it, you can buy it if you don't open it.

The iPhone 4 is not yet a refurbished machine. IP4 is so good that many friends won't get rid of it, unless there's a problem...

Then you might as well try your luck and get a brand new one. Treasure hunting, activate the account to have a chance**, the prize is iphone4.

If you're looking to buy licensed goods, then I'm telling you, it's absolutely fake. Because the price of licensed goods in major cities in Chinese mainland is like this: 4999 yuan for the 16GB version and 5999 yuan for the 32GB version.

This is the price I only learned when I went to buy it myself. I'm also a fan of the iphone4, but for us salarymen, licensed goods are luxury, so I buy domestic machines (better than copycats). I just bought a Taiwanese version of iPhone4 today, priced at 1199 yuan, white.

It feels pretty good to use.

If you really want to buy licensed goods, let me tell you, the main thing to distinguish between the real and the fake is the parameters, the processor of the genuine product is the Apple A4 processor, the material is tempered glass, the resolution is 960*640 pixels, and the pixels must reach 5 million pixels. In addition to the genuine ipone4,No other machine can reach this level,There is**,Generally**16GB below 4500 should be vigilant。 As the saying goes, you pay for a penny, and if you want to buy a good one, don't be too afraid to spend money Remember.

This price will definitely not be able to buy the best iphone4, now the Guangzhou mobile phone store, 9 new ** will be more than 3,000, if the boss is really 1200 on the **iphone4, then I can go wholesale.

Definitely not **, iphone, you can't get the price of buying 3 generations and 2 hands.

The most direct way is to open your computer and connect to iTunes and see if you can connect to it.

The cost is more than 1200 yuan, so don't be greedy. You see if you can play big games, like CS or something.

I think it's very likely to be fake, so pay attention, the easiest way to tell the real is to play a big game.

Second-hand Apple Four, it should be around 3000 yuan. 1200 impossible.

1200?9 percent of second-hand hands are above 3000, and they may not be received.

It's certainly not true, don't be fooled.

Do you think it might be true?The refurbished iphone 3 is still 3,000 years smaller.

To verify that the phone is not **, please provide the serial number, phone settings - general - about the phone, you can see.

Or provide IMEI code, mobile phone dial*

The iPhone screen should be well protected and not fallen. For the rest, as long as you verify the phone, there is no major problem.

The precautions for buying a second-hand iPhone4 are as follows:

1.Pay attention to the serial number. Generally speaking, the three-in-one is usually **.

2.Look at the appearance. It is best not to have a defective appearance, so as not to have sequelae on the mobile phone (it will not be able to turn on one day afterwards, in fact, the motherboard is damaged).

3.Connect iTunes and Master Lu to verify authenticity. The genuine function is recognized by iTunes, not by Master Lu. And the copycat function is recognized by Master Lu, not iTunes.

4.Look at the warranty. Generally, do not buy the machine that is out of warranty, so as not to spend a lot of money to repair it when there is a big problem in the future, and you have to spend money to replace it with a new machine if you don't repair it well.

After using it for 2 months, it doesn't need to show that he can see that there is a problem with the machine, understand.

The first Hong Kong version of 8G, at present, iPhone4 only 8G licensed, the other versions are refurbished, and the refurbished is relatively good in the official copy.

Second-hand has the advantage of **, but the quality is not guaranteed, and this can only be identified by yourself.

Support continues to ask questions, help you analyze, and help you solve problems.

It's all refurbished machines as long as it's not a problem Since you plan to buy second-hand Most of them are refurbished Generally, the current 4th generation is unlocked Buy 16g is a good point 8g can't fit a few things After all, some software has 1g You can only distinguish from the appearance Secondly, you can ** battery record query battery only use records.

Each product released by Apple has a serial number, and each serial number records the model, color, production date, version, body memory and other relevant information of the Apple product; You can go to Apple's official website to check the serial number, Apple's warranty period is 1 year from the date of purchase, if the query shows the same purchase time as the actual purchase time, no problem.

Since YouTube has been blocked in China, the YouTube icon will not appear on the first screen of the licensed iPhone 4. Some people think that it is impossible to get this icon out by updating the version, but it is found to be impossible after experiments, which means that licensed goods will never be able to get YouTube clients. It can be said that the absence of the YouTube icon is the main sign to distinguish the real from the fake.

Secondly, all the accessories of the licensed goods have a very small but clear manufacturer's logo.

From my actual experience, the bezels are bound to be scratched, and the same goes for wearing condoms. There must also be flower spots on the back cover glass. You can ask for the serial number activation date through Apple customer service.

As long as the activation date is the most reliable, because the front and rear glass and frame can give you a brand new one, it is not worth the money. It's the movement that counts. Second-hand is so expensive, there is no big loss.

Remember to go unlocked.

There are too many accessories for the iPhone 4.

The shell can generally be replaced.

What's inside can also be initialized by a software refresh.

Clever profiteers won't let you find out it's a refurbished machine.

Just use it yourself, there's no need to worry about it so much!

Headphone jack.

If it is not unopened, it cannot be considered an absolutely new machine.

The box is opened, and people take it out to play a few **, and you don't know anything about brushing a system or something like that. Then we experimented with one by one, and put the noise on one side, and the non-noise on the other side.

Sell different ** separately.
