Anonymous users2024-02-091. The U.S. version has $199 and $299, but they are all like the contracts of local operators, just like the contract machines of China Unicom; The U.S. version is also unlocked, starting at $649;
2. The locked version can be unlocked by the card, which is basically the same as the unlocked version, the main difference is that it needs to be unlocked when it is turned off and then opened; Whether you can jailbreak depends on the system version, for example, the latest one can't be perfectly jailbroken, and other versions can be perfectly jailbroken;
3. The card is unlocked by using some rules on the operator's network, and it basically has nothing to do with the system version, so now all versions can be unlocked by the card, unless Apple wants to block the card;
4. No, now the iphone4 market is chaotic, beware of refurbished machines.

Anonymous users2024-02-08Use Stickers:
The card is an unlocking tool used by the mobile phone when it cannot be unlocked with software. For example, if you want to use the Japanese iphone4 with softbank network lock in China, put the Chinese SIM card and card sticker together in the mobile phone, the mobile phone will be authenticated when the mobile phone is turned on, verify whether it is a softbank card, and the mobile phone will read the content of the card chip, because the chip has the information to verify the mobile phone operator, so the mobile phone will mistakenly think that it is using a softbank card, and after passing the verification, it will start to search for the signal, and the Chinese SIM card can be used. In principle, the card sticker is actually the same as the principle that many game consoles can't crack at the beginning and need to use a boot disk.
Advantages and disadvantages of using card stickers.
Due to the hardware-based "information spoofing" of the card, the advantages are obvious, and it will not be invalid due to the upgrade of the iOS software version under normal circumstances.

Anonymous users2024-02-04The unlocked version means that it is not restricted by the operator, and the SIM card of any operator can be inserted into the normal use. The unlocked version allows you to upgrade the firmware at will without having to worry about signal cracking.
The locked version refers to the addition of a network lock, that is, the operator is bound, so the mobile phone can only be used normally if the SIM card provided by the operator is inserted, and other cards cannot be used if you want to use other SIM cards. Be cautious when upgrading the firmware of a locked iPhone, because some basebands cannot be unlocked.
The easiest and most straightforward way to tell if there is a lock is to verify it with a SIM card from another operator to see if it can be used normally. If there is a signal, it means that it is unlocked, and if it is not, it is locked.
If you don't have a SIM card at hand, you can use the method of querying the model to identify it.
If the iPhone4 is a baseband, iPhone3GS iPhone3G, and baseband, it can be unlocked with the UltraSnow UltraSN0W version.
Query baseband method: Open "Settings - General - About This Mac - Modem Firmware" of your iPhone

Anonymous users2024-02-02The U.S. version also has a kind of soft delyser that is directly unlocked through the software.
The first step to do is, of course, to press and hold the power button on the top of the fuselage to turn on the power (it cannot be activated when it is turned off). 3 A familiar "white phone recharge card" is presented on the screen, and if you have failed to jailbreak, you should be familiar with this interface. After waiting for about 20 seconds, the iPhone will automatically enter the lock interface, and the unactivated iPhone 4 will be in full English for the time being, and the screen will prompt the user that the SIM card is not inserted in the phone, and ask the user to connect the iPhone to the computer and open iTunes to activate it. >>>More

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. >>>More
