Hello landlord.

Let me give you my advice and advice.

It is useless to explain too many reasons, the landlord can learn slowly and read different posts.

My conclusion: there are only the following that can be purchased:

Bank of China bare metal (** or electronic city purchase), Hong Kong bank (** or electronic city purchase), Bank of China contract (Unicom purchase) Don't think about what is a locked version (US version, etc.). It was not suitable for Chinese.

The key to my answer to your question is to tell you, don't buy the US version (that is, the locked version). If you don't plan to contract with China Unicom, or are reluctant to buy the bare metal of the Bank of China, then buy the Hong Kong version, and the Hong Kong version is recommended.

It is impossible for the Hong Kong version not to open the package, and you must open the package to enter the country, but I hope you can calm down, since you don't spend more money to buy the National Bank, the Hong Kong version of an unpacking is too indifferent, people are doing business, they won't move your machine, and if you believe it, you will buy it, and if you don't believe it, you will abandon it.

So, no matter if you have money or not, don't miss the hundreds of dollars, don't buy the American version. It's very good to buy the Hong Kong version. Today's new machines are generally system is or.

PS: If you insist on buying the American version. For example, you will not dare to upgrade the latest system for life, and you will have to install software carefully for life, if there is a problem, the consequences are very serious, you are in China, you will not be able to play ** and text messages. And our national bank or Hong Kong bank can be tossed at will.

Finally, the targeted answer, the so-called whether there is a lock, the lock refers to the lock operator. That is, the locked version of the American version, the mobile phone can only recognize the SIM card issued by the local communication operator in the United States, while the unlocked version like China and Hong Kong can identify the operator of any country. It has nothing to do with card cutting.

Cutting cards is just that the iPhone needs a small card, and the shape is different.

It can be completely literated and the same as in China.

That's a very simple question.

The U.S. version has a lock that means that this iphone is a mobile phone customized by an operator in the United States, and there is no signal or some functions can be used when other mobile phone cards are put in, this lock is a network lock, it is a software, such as the first largest telecom operator in the United States AT&T customized iphone to take it back to China and put the domestic card into it is not signal, because there is a lock inside, this lock only knows AT&T card, can only identify his signal, if a foreign machine wants to be used in China, it must be unlocked, At present, iPhone4 has not been able to unlock the software, can only be unlocked with a card, software unlocking is to use third-party software to destroy the network lock, the phone into no version, but at present can only be unlocked by software below 3gs, iPhone4 can only be unlocked with a card for the time being, the principle of card unlocking is: there is a small chip on the card, he can let the phone CPU directly read the SIM card, so as to bypass the network lock, so that there is a signal, but the card unlocking trouble, It's okay to switch between airplane mode and standard mode often, you know??? If you are good at programming, hurry up and develop an iPhone4 unlocking software, so that parallel imports can be used very well.

The locked version is to add a network lock, that is, to bind the operator, such as the American version of AT&T, the British O2. Such a mobile phone can only be used by inserting the SIM card of the corresponding operator, and it cannot be used by inserting other cards. Normally, the purchase of this type of iPhone is through signing a 1 2-year network access agreement with an operator, binding a credit account to promise how much to spend a month, and buying the phone at a discount or giving it away for free.

In this way, the mobile phone cost of the iPhone has been converted into the phone bill of the corresponding carrier. If you want to use a different card, then the iPhone needs to be jailbroken and then unlocked. Only through these two processes can a locked iPhone use another carrier's card.

Regarding unlocking, it is also divided into hard unlocking and soft unlocking. The unlocked version is also called the official unlocked version, such as the unlocked version of Hong Kong or the UAE (Hong Kong also has Hutchison's "3" customized version of the iPhone). This kind of mobile phone will generally be relatively high**, but the advantage is that the SIM card of any operator can help the iPhone activate smoothly and be able to use normally.

They only need to be jailbroken and do not need to be unlocked.

It is bound to an ATT operator in the United States, and the cost of unlocking it in China is still relatively high. It's better to buy licensed goods directly.

If you unlock it, you need to install a card on the SIM card.

There is a lock that cannot be used in China, it is equal to a brick, but now it is very good, and it can be used with a card. Stick a few hundred dollars. Apple iphone4s 16g American version has locks, which are rarer than those in Hong Kong, and it is not easy to buy.

Apple iPhone4S 16G American version has a lock, which is customized by American operators and then used in the United StatesiPhone4s.

If you want to use the American version of the locked iPhone4s, there are only two ways:

1) Operator unlocking, which can generally be done at the expiration of the contract.

2) Card unlocking, most locked iPhones are unlocked through this method.

It's equal to a brick and you can listen to songs.

The American version of the custom machine is good to unlock.

1. It's okay to upgrade the baseband, but it is still recommended not to upgrade, no one knows whether the firmware has been changed or not, and the upgrade of the baseband has been removed.

2、I've never seen this kind of situation.,I'm IP4.,My jailbroken fruit ninja has been playing for a long time.,The official doesn't know how many times it's been updated.,You can still play.。

3. There will be no problem with the signal, unless you change the baseband of the iPad to unlock, then the signal will be worse, and the GPS may have a significant decrease in accuracy, or even not use, but the signal of the iPhone is not good, and you don't have too many expectations.

4、The thing to pay attention to is to see the itchy hands.,Even when the computer is always someone careful to give a little upgrade.,Once the upgrade is direct.,It seems to be a complete brick.,I don't know if the newly launched card can solve the system.。

U.S. version of iPhone 4: Apple iPhone 4 mobile phones sold in the United States, with the end of the model number LL A or LL B, and the FC certification pattern on the back, divided into locked and unlocked.

Locked iPhone: You can only use a fixed carrier card, and you can't use an iPhone with another carrier card.

Unlocked iPhone: An iPhone that can use three operator cards: China Mobile, China Unicom and China Telecom (the telecom card must be realized through the apple peel after installing the apple peel, otherwise it will show no service).

Suggestion: It is best not to buy the US version with locks and without locks.

The U.S. version has the following disadvantages:

1. It cannot be warranted in any country other than the United States, but only in the United States.

2. You can't upgrade randomly, after upgrading, the sticker will be scrapped and cannot be used, and you need to re-purchase the card of the corresponding firmware to unlock and activate.

3. Some of them are contract machines, and the cards of other operators will be locked by the operator, and the mobile phone can only be unlocked if you need to pay a liquidated fee.

4. After the prison escape, you can pretend to be a national bank machine, which is a parallel trade into a licensed product, disrupting the market order.

The U.S. version of the unlocked machine has the following disadvantages:

1. It cannot be warranted in any country other than the United States, but only in the United States.

2. It's cheap when you buy it, but it's also cheap when it's second-hand.

3. Some mobile phones are unlocked through jailbreak (some unscrupulous stores are used to tricks), and the network is restored after flashing, and a card is required to use the ** function.

4. After the prison escape, you can pretend to be a national bank machine, which is a parallel trade into a licensed product, disrupting the market order.

There is a lock is a machine customized by the network operator,No lock is the world's universal WCDMA machine,You can't change the operator" There are several ways to unlock such as what card is not very clear,Jailbreak should say that it is brushing root,It seems to be the release of device function permissions,System upgrade performance or something should be the same,

The American version of the unlocked version is a lockless version, but you can't erase all and flash the machine, or it will become a locked version to use the card The American version of the locked must use the card Sticker** is about 50 But with the card every time you shut down and restart the card to reset the card It's very troublesome So the American version of the lockless is not really unlocked, but you can't use the card to realize the random flashing of the unlocked machine.

iPhone4 US version: It was sold in the United States, and it went to China through some means (that is, parallel imports...).

The difference is:For example, at that time, iPhone3GS didn't have a Unicom version,You can't use a mobile card,This is a lock,No lock is of course better than a lock,At least it's not troublesome,If you're not afraid of trouble,You can buy a lock,It's a lot cheaper,But the function is the same,Now there's a card,You can unlock,If you don't unlock,It's a touch with a pixel high.。。。

It's best to buy a Hong Kong line.,About 4000 absolute can be done.。。。

American version - everyone should understand that it refers to the region, I won't say more.

Locked - refers to the operator to be fixed, such as China Mobile Communications, China Unicom, China Telecom CDMA, which operator can only use the card of that operator. You don't have a choice.

Non-jailbreak – a perfect jailbreak that has not been cracked so far and is impossible to crack in the short term – is one that has been cracked and has been tested over a period of time.
