What does it mean when iPhone 4 has a lock without a lock?

The lock is the only thing you can do with the card that you put in your iPhone when you bought it. No lock is that you can use any card.

WhatsApp is a software that allows you to send SMS and MMS messages to iPhone users for free. And only those who have downloaded this software can communicate with each other. And that talk box...

It's also a lot of fun. It's like a walkie-talkie. It's also free.

The requirement is also iPhone users and they can communicate with each other under this software. And a viber....Hehehe.

This bull is bout. Free** plus SMS. But those 3 software.

All you need is your iPhone to be connected to the Internet.

Locked means that only the SIM card of the specified operator can be used, and no lock means that all SIM cards can be used. The function of the iPhone can only be used if it is activated, which is to connect to the computer and connect to the Internet through iTunes.

Licensed goods are unlocked regardless of whether they are tied or not, and the new machine can be used when it is activated by connecting it to the computer. Parallel goods are locked, and if you want to use a new machine, you have to unlock it first, which is not very troublesome, but you can't update your machine with the update speed of the official website, because the unlocking patch may be delayed.

The locked version is a machine with an operator lock, which cannot be used directly when it is taken to the mainland, and must be cracked (soft or hard decomposed). Only by untying this shackle can it be used at will. Activation means that each machine must be activated at the beginning of use.

With a lock is to limit the operator's iPhone, you can only use their SIM card, and there is no limit if there is no lock.

If you don't lock the version, put it in the SIM card and you will be prompted to activate it. Just connect to the computer and confirm.

Whether there is a lock means that foreign iPhones such as the United States and the day cannot use domestic mobile phone cards.

Activation is to connect the phone to the computer and register it with your iPhone.

16G now seems impossible to become 32G,The reason is that the encoding on the machine corresponds to the 16 or 32G information in the Apple server,Now the machine is brushed,You have to go through Apple's server,So after you make it32G,Apple server will not allow the flashing to continue。

No lock, no jailbreak, you can use any SIM card", which means that you can check any non-telecom card to play**. If there is a lock, you need to install the unlocking software after jailbreaking, and the signal will appear after inserting the card. Therefore, it is recommended to buy a lockless one.

Hope it works for you.

The lock is a network lock, which is a way to restrict users from choosing an operator, for example, Apple and AT&T have signed an agreement, and the iPhones sold in the United States have AT&T network locks, so you can only use AT&T's SIM card, of course, you can also unlock it, but there are many restrictions, mainly including:

1. Unlocking is more cumbersome, more troublesome than jailbreaking, and requires more things. You key to the world.

2. The firmware cannot be upgraded casually, because the baseband will be upgraded as soon as the firmware is upgraded, and the lock will be locked, if the firmware is newer and not unlocked, it will not be able to be used, and if there is no universal card, it can not even be turned on, that is, it can only be used as an iPod touch, and it cannot be used to play **, communication.

At present, the network lock does not have a lock only the British version, the Hong Kong version and the mainland Unicom version that will be launched soon. It should be noted that some black-hearted traders will change the national version of the beauty god limb (cheaper) iPhone to an unlocked version to sell, which is a high risk and unreliable quality, so you should pay attention to identification.

--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.
