Can iphone3G be upgraded to IOS 4?

The highest version of the iPhone 3G is that it can be upgraded now, because at present, only the upgrade and downgrade of the iPhone 3G is not limited by the server, and the machines that come out after the iPhone 3G must be verified by the server! My iPhone 3G was used when I bought it back, and I swiped it myselfNow it's for my wife!

You can rest assured! (But I still want to tell you a little bit, after brushing from the iOS3 system to the iOS4 system, there are indeed a lot more functions, but due to the relatively low hardware configuration of the iPhone 3G, it does feel very stuck to use).

Finally, I wish you a happy game!

Yes, the steps are as follows:

1. Make sure you have installed the latest version of iTunes

2. Connect your iPhone to iTunes

3. Make a backup of your iPhone via iTunes on Mac or PC. iCloud backups can't be reverted to earlier versions, including iOS.

5. Hold down the Option key on your Mac and click "View Updates". Or hold down the Shift key on Windows and click "View Updates".

6. Click "Update" to install iOS 4 on your iPhone.

Now the iPhone 4 phone can be upgraded to iOS system version normally.

How to upgrade the system of the iPhone phone:

1. Click to enter "Settings". Click to enter "General";

2. If there is a new version of the system, the word "1" will appear after it, indicating that the system can be upgraded, find "Software Update", click to enter; If not, it means that the mobile phone system is the latest version and does not need to be upgraded;

4. Click "Agree" in the lower right corner of the "Terms and Conditions";

iPhone4 can now be upgraded to the highest version but it is recommended not to upgrade, now it is impossible to downgrade after upgrading to iOS8. The iPhone 4 can't afford it now.

Once you upgrade, it's over, don't upgrade.

1. Go to your phone's settings General About This Mac, and then click "Network", and the carrier update reminder will automatically pop up, click the "Update" button.

2. After the update is completed, the operator configuration will be upgraded from "China Mobile" to "China Mobile". Then, click Settings, Cellular Network, and Enable 4G to complete the update operation of upgrading your iPhone to 4G network.

Hello, Apple 3G network replacement, first go to Settings, select the network, and click Priority 4G network.

Note that if your iPhone is a 3G phone, you can't change to a 4G network, you need to change your Apple 4G phone to use the 4G network.

You can tap Settings, select General, tap About This Mac, and check the specific model of the phone and whether it supports 4G networks. Since the fifth generation of Apple, it has supported 4G frequency bands.

Hello, it is not supported because the hardware device of the Apple 4 phone does not support it.

At present, only 4 iPhones support China Mobile's 4G 3G network

China Mobile contract version iPhone5S 5C, the specific models are: A1518, A1516.

Apple's official public retail no-contract version of the iPhone5S 5C, the specific models are: A1530, A1529.

You can check it in the lower right corner of the back cover of the phone. If you are a Beijing Mobile customer, you can activate the 4G function SMS by sending "KTSG" to 10086, and you can activate the 4G function for the local USIM card, which will take effect in the current month and will not be accepted after 7:00 p.m. on the last day of each month.

If you are using the Hong Kong version of 5S 5C, you can only support mobile 3G and 4G networks after upgrading the operator version or cracking it, you need to note that if you are using Mo or Shenzhou Xing unlimited traffic**, it is not recommended that you upgrade the operator version. Please refer to it.

Not supported. 4S only supports mobile 2G

I want to too, but it's impossible, I want to use 3G to choose Unicom, if I want to use mobile 3G or 4G, then Apple 5S and 5C are a good choice!

Resolutely not rising! It's already very stuck.,It's even more stuck when you go up.,I've tried to rise.,It's not happy.,And the game of a big pin is basically still not playable.,Wings of Holy War.,Angry boss bees and the like will pop up as soon as you enter.。

2.If you want to unlock it, the baseband is to be upgraded together, but the firmware can be used to go up and down, and there is no problem that you can't get back after going up and down. So there is no need to back up SH, the baseband really can't come back when it goes up, and it's the iPad baseband that goes up, which will have an impact on the signal.

Upgrade words:

Install the upgrade directly with your phone in the wifi case.

This method does not require the use of iTunes software, open your phone's Settings - General - Software Update, and if you have enough space on your phone, you can choose to install the update. Note 1: During the upgrade process, the mobile phone must have enough power, and the wifi signal cannot be interrupted, otherwise it is easy to have problems.

Install and upgrade your computer.

After getting to the interface in Figure 2,

No, mobile phone hardware is not acceptable. The Apple 5s can also be upgraded.

Yes, hang the Apple 4 to **second-hand, or sell it directly to those who need it, and then add money to buy an iPhone6 or 5S, so that you can upgrade the 4G perfectly, otherwise there is no other way.

No, there is no hardware support.
