The difference between iPhone 4 with lock and without jailbreak how to understand

In fact, the commonly locked version is that the local operator binds the mobile phone to the card, and no other mobile phone card can be inserted, so it has to be unlocked, and it can be used all over the world if it is unlocked. (For example, if you buy an iPhone in the United States and can't use it when you return to China), this is called a locked version. There is also an unlocked version, there is no restriction on mobile phone operators when it is released, you need to buy it at an Apple store, and the price will be much more expensive, but the unlocked version does not have to worry about not being able to use it back in China.

The things that run on the locked version and the unlocked version are exactly the same. In addition, the iPhone 4 is also available in the United States, the United Kingdom, Hong Kong and the Asia-Pacific version. For example, the Hong Kong version issued in Hong Kong is called the Hong Kong version, and the Hong Kong bank refers to the licensed goods in Hong Kong, and the real Hong Kong bank can also enjoy the national warranty on the mainland.

As for the American version, it is actually a parallel import, smuggled in from the United States, **cheap, and the quality of the things is good, but because it is a locked version, it needs to be cracked before it can be used. The British version is an unlocked version, and you don't need to crack it, it's just too high. However, it is understood that Unicom will launch the Unicom version of the iPhone 4 on September 16, which is not high in comparison, and it does not need to be cracked, which is worth paying attention to.

At present, the American version in the market is more common, and it is the cheapest compared to other versions. However, since it is a locked version, it needs to be unlocked. So users who want to save some money and like DIY and are not afraid of trouble can choose the American version of iPhone 4, because there are jailbreak tools and unlocking tools, even if it is not perfect now, it is a matter of time before it is cracked.

However, because it is a parallel import, if you choose the American version, you don't support the national warranty, and you can only look at the character. However, Apple's brand is a guarantee of quality, and there should be no major problems.

--About the difference between locked and non-locked.

Because of the partnership between Apple and mobile operators, the contracted IP of a specific operator in some specific countries and regions is bound to the operator, that is, only the SIM card of the authorized operator (such as AT&T, Vodafone, etc.) can use the mobile call and coherent functions of the contracted IP, and other SIM cards cannot be used. Only after unlocking the locked version of the IP can you use the SIM card of China Mobile and China Unicom in China and obtain call and coherent functions. If there is a locked version, please upgrade the firmware carefully.

-This is an iPhone4's, not a 4s---

1. At present, 80% of the world's iPhones are made in China (Foxconn). The difference is that there is a lock and there is no lock.

The most common iPhone 4 on the market mainly includes the Bank of China, Hong Kong version, American version, Canadian version, Japanese version, Macau version, Taiwan version, British version, Singapore version, etc. The contract machines of the United States, Canada + some Asia-Pacific countries + most European countries + Latin America and the Caribbean are locked machines, and some Asia-Pacific countries + a small part of European countries are locked.

2, as for **, of course, parallel goods are the cheapest (because he is a contract machine with a lock, and the contract machine over there can basically only use AT&T, Vodafone and other operators' cards.) When you come to China, you need to unlock it to communicate, and it is basically smuggling), followed by the Hong Kong Bank (because of the exchange rate and official taxes, 4999 Hong Kong dollars = about 4200 RMB), and then the National Bank (4999 yuan). <16g, 4s before release".

3. Distinguish by looking at the model, not by looking at the serial number.

At present, most of the 603 is 16g, and the 605 is 32g.

For example, this model MC603CH, 603 is 16G. The chuckle behind is China.

ZP for Hong Kong and Macau, TA for Taiwan, ZA for the Asia-Pacific region, LL for the United States, C for Canada, J for Japan, etc.

It is recommended not to buy online, the cat is too tired, and it is not much cheaper. The best version of the licensed,The price is hundreds more expensive,Because it's the only version with a warranty,You can use all the software for free after jailbreaking,It costs money if you don't jailbreak,But basically you can't shut down after jailbreaking.,Power consumption is also larger.。
