How to identify whether the American version of the unlocked iPhone 4S bought online is refurbished

Second, even if it is three codes in one, it does not necessarily mean that he is not a refurbished product, and online shopping for mobile phones is taboo.

Third, even if the system has been replaced, as long as the activation time is advanced, it is enough to indicate that it is a refurbished machine, Apple is not Nokia, don't underestimate Apple's software engineers too much

Fourth, Apple's serial number, activation time, and warranty related data are automatically uploaded to Apple's official server after the device is activated.

Fifth, your worries are purely demonic, the first time you buy an iPhone, ask:

Open Settings - General - About This Machine Find the real serial number (the packaging of WhatsMiner can be fake), go to the official website to check the warranty period through the serial number, the warranty period is pushed back one year for the activation time, as long as it exceeds a few months or even half a year or even the warranty expires, hurry up and return it!

That's my advice to you:

Oh more than the warranty period should not,4S has only come out for a year and hasn't arrived,I'm just worried that it will change some firmware (such as touch screen and the like),So even if you check the serial number,Can't find these out,:Layman first,iPhone4sThe retina screen can't be made by general copycat manufacturers,Even if you change it, it's the original factory.,Big husband

Second, it is not called firmware, it is called parts, and firmware refers to system software.

Third, even if it has been listed for less than a year, half a year? Nine months? Are you at ease? You're so easy to deceive.

Fourth, how many cats are in the js refurbished machine, will I tell you? Oh asked:

You'd better tell me a little bit, hehe

Have all parallel imports been activated in advance? ：

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.

The official website link is as follows.

The way to buy the American version of the unlocked iPhone4s on Apple's official website in the United States is to log in to the official website of Apple in the United States and choose to buy.

However, this mobile phone has been discontinued, Beijing time on September 11, 2013 at 1 a.m., Apple held an autumn new product launch conference in Cupertino, California, USA. The iPhone 5S 5C was released, followed by the iPhone 4S and iPhone 5.

I'm in the U.S. myself. There are only two ways to buy an unlocked version of the 4S in the United States. The first is to buy a no-contract version of the 4s at the Apple store, which costs $650 + tax.

The other is to buy the 4S of the ATT contract machine. Note that only ATT's contract machine is available. There is a data cable, earphones, and a charging plug in the box.

The original pinyin input method of the machine. Have any questions qq me. 375512671

The American version of the unlocked version is best bought at the Apple store, pay attention to the store! The one there is imported from the United States, be careful to buy the cracked version!! It's a computer keyboard input method.,Sogou can only be installed and used after jailbreaking!

The U.S. version is unlockless, and the card is ready to use after cutting! The headset charger comes with the original.

The U.S. version needs to be decoded before it can have a pinyin input method,Otherwise, it's all English.。

The stupidest and easiest way is to take out the card tray (a small card that puts the SIM card), if you don't put anything to read the card, it means that it is unlocked, if you want to put a small copper sheet to read the card normally, it is locked.

Now 4s are cheap. Don't go buy the American version. In my opinion, all apples. The American version is the worst to use. Buy a Hong Kong or a national bank. It's not too much of a difference. Besides, you have to upgrade the jailbreak in the future. There are not as many problems as the American version.

No card sticker, that is, no lock machine.
